I'm also of the opinion that it's OK to use game editors to counteract bugs, such as the Gharik's Lab Key bug, or to compensate for the loss of of reaction time caused by the bugs in the armour skills.

The tools of helping out bugs are of course necessary to keep the game intact.

BUT my point might be that, if someone is remotely complaining about, how easy or short the game is, and at the same time takes advantage of every single exploit there has ever been recorded, then it is not at all fair to the game.
For instance you take advantage of the Shrine of the Gods directly from day one, visit the NWC offices to get lots of gold, mix all black potions for each character, solve all the easy-to-do promotion and council quests to gather lots and lots of experience, collect all horseshoes to put them into Water magic, multi-load to get what you want from corpses and shops, fly up and down to avoid ranged attacks, reload every time you don't like the outcome of a battle... or just one or a few of these tricks.

And no, I'm no saint, I cheat as well but on my own terms - some I do occasionally and some I never do. The shortcut to Dragonsands doesn't exist in my book and never will (it's only an easter egg to me - I visit NWC usually just before the Hive but only as a completionist), I collect the quest awards in a linear way (I haven't collected the Knight's nomination or reported back on the finding of the Fountain of Magic, in my current game yet - has also something to do with the fact that training gets a lot more pricy after that), I multi-load to find the spell books I need, I multi-load to find the NPC's I need, I multi-load magic shops to find items of each regeneration for every character and nothing else, I don't multi-load corpses - unless I find an unwanted artifact/relic, I only reload if my team dies in combat (thus Guardian Angel is a useless spell to me), I have given all my horseshoes to my sorcerer (but she has also got expertise in Fire and Air magic and Identify item simultaneously, hasn't got mastery of Water yet and I have visited neither Blackshire, White Cap nor Silver Cove only to collect the horseshoes), I accept the enchantments that my Enchant Item presents me, I rarely use the Circus, hence I don't resort to Abdul for good stuff, I have mixed a bunch of black potions but only to save space in inventory (also I have still got a few fountains or wells of +2 permanent stat to visit), I feel bad about flying up and down when fighting (I might very well use real strategy this time around) - this way I feel I get the most out my game.

And yes, I've paid more than once for my games, I own both hard copy and GOG version of most of my 3DO games, have back-up cd's (bought used) as well - also have a few in collectors edition.

In a battle, I reload only when I'm completely wiped out. I don't mix Black Potions, because I don't know how to do it and I can't be bothered to find out. (I generally don't search for recipes, locations of things etc. in books or on the Internet. I don't play MM6 that often, so I just write things I find on a piece of paper.)

I don't do any multi-loading at all. The beginning is the most interesting stage of the game, I guess, because it's different every time . The endgame is always the same. I do keep the results of my Enchant Item, because I know that the enchantment will be crappy anyway, and so I mostly enchant any regular trash loot just before selling to make a bit more money out of it . (Actually, the loading is so boring that it just doesn't pay off for me.)

In combat, I do fly around in real-time, but I don't fly up and down in turn-based mode.

And I've never heard anybody complaining about MM6 being easy. However, I remember that in one of the old Czech magazines about PC games, there was some whining about how the game is unbeatable even with cheats.

In short, I just play the game to have some fun, wandering around the country, doing quests and so on. I don't try to "max out" too much. In fact, in my first game, I missed a good bit of the game (obelisks, Dark/Light magic, also I found a lot less artifacts and relics, I didn't do anything at Circus etc.) So I at least had something more to do in the second game .

I prefer magic-heavy parties, but not pure magic ones, so my default parties in MM6 are APCS or ACSS, but occasionally DCSS.

APCS is the party which has the best "fit" to the artifacts, relics and other goodies available in the game. You can acquire two copies each of Morgan, Igraine, and Guinevere, so the Archer gets a Morgan, the Paladin gets one Igraine, the Cleric gets the other Igraine and one Guinevere, and the Sorcerer gets the remaininder, Guinevere and Morgan. Nothing wasted. The Paladin gets Hades, and the Archer, who cannot use a shield, gets Poseidon. This party is pretty well self-contained, and doesn't normally need to make much use of the Temples' healing capabilities, even when utilising the wells etc, which kill, stone, or eradicate the characters.

ACSS is capable of doing much more damage, especially if you use the v1.0 exploit which allows the druid (and the Archer if you feel like it) to use Dark Magic, and there is another exploit which allows the druid, sorcerer, etc. to use heavy weapons and heavy armour. However, I don't normally utilise these. Although it is much more lethal, this party needs to make rather more use of curative scrolls or the Temples. It also cannot make full use of the lovely armour and weapons that are found. When using two sorcerers, I concentrate on building up the Water Magic skills for one, and the Air Magic skills for the other.

I normally use two NPCs, a scholar so that I don't require the identify skill, and an instructor, to boost XP.

I routinely Mephisto the cadavers of high-level monsters to get the rings I want, but I rely on the natural occurrence of boots, helms, gauntlets, etc. to provide the other boosters to improve resistances and regenerate hit points and mana. My most-used combat spells in this game are Shrapmetal at contact range, and Ring of Fire. I tend to use ranged combat whenever possible, espcially when fighting monsters which age or drain the party.

I tend to use the teleporter to Dragonsand fairly early – usually when my party is at level 12–16 or thereabouts – but I don't usually zoom all over the map to collect horseshoes early. I have done so on occasions, though, and when I've done this, I've hired a gatemaster and visited all the reachable fountains so that Town Portal works fully as soon as I get it.

I've usually run with PSCA parties in MM6 and MM7; which as you point out is a good combination strengthwise and fits well with the artifact/relic selection in the game.

Currently I'm running a KSDC party as an alternation - it's nice to have a Druid who benefits from all seven stats for a change. On the other hand the Knight only benefits from five stats, but he's immune to SP drain and also to insanity in a certain way. xp Also he comes with 10 rare magic resistance points. Of course as I recently learned from this board, personality and intellect affects the chance of getting cursed and insane respectively, so the points are not all useless - though it is close. My Knight takes care of disarming, repairing and perceiving. My Sorcerer takes care of identifying and my Cleric takes care of selling/buying which have always been my preferences. My Druid concentrates on the use of magic.
No diplomacy for me - can't remember if I ever used it :/ Anyone?

But in terms of your question, the game obviously doesn't know "common sense" - ie just because all crossings along the north border lead to A, and all along the west border lead to B, then the exact corner point should lead to the area between A and B. That would have to be specifically coded, or the game would just pick whatever border it felt you were closer to. So yes, seems to be something the developers intended.

I can't remember how I came to learn this in the first place - I've known this trick for at least ten years - maybe I read about it before trying it out, or maybe I found it by roaming about in a game long ago.
I know I did roam about a lot in my earliest games (looking for out of reach chests and stuff), so maybe I did find it on my own, thinking everybody but me must've known this already - thus I never thought of sharing it :/

Once a party gets Water mastery it is not a very useful trick in the book. But I reckon that this would be super knowledge to a party of all Knights, Paladins, Clerics or any mix of the three, or even for a solo/duo of one of the three.
