The game allows you to find 13 artifacts in total before it stops giving them, so the way to do it is to get your 13 random artifacts before going after any of the placed ones. That way, you can get 18 artifacts for your party.

I too have had to replace my computer recently, which entailed moving to Win 10, and I didn't know if I could install the games from my old MM6-9 disks, so thank you for that information. I guess GOG is going to get a customer! However, I also want to see if I can transfer some of my old DOS games and run them under Dosbox. I want to see if I have enough digital dexterity left to play Eye of the Beholder and Legend of Darkmoon again.

With Windows 10, it does seem somewhat random: I've seen posts here about having simply tweaked compatability settings and getting these games up & running, but no such luck for me. It's the copy protection on the CD versions of games from that era that causes the problem, apparently: it creates a security vulnerability in Windows that was "fixed" with an update in Windows 8, and this update broke these games, but at least you could uninstall the update if you chose to live with the security flaw. With Windows 10, this "fix" is baked into the OS - Windows is completely aware of the issue but made a conscious decision to remove the security flaw even if it broke games. People like us still playing these older games are a diminishing population, unfortunately!

I can confirm however at worst if you're similarly unlucky with compatability settings that the GOG versions of both Wizardry 8 (after downloading the separate "fix the GOG version of Wizardry 8 for Windows 10" patch) and M&M6 work perfectly. The only thing, like I say, is that you're stuck with whatever patch/version it is, because none of the old patches that we have all had for years will work on the GOG version - it's a completely different exe file. I can also confirm that DOSBox works just as well under Windows 10 - I downloaded Pool of Radiance and played it completely through under DOSBox with no issues.

Some small goodies it adds: a bit of additional info accessible in the game (for instance you can check your recovery times with a right click on your Attack/Shoot bonuses), a quick save, an always run feature, a double speed feature (good for traversing the vast landscape fast), a possibility to play the music from MP3 files in a given folder (instead of the CD playback which often just won't work nowadays) etc. It also makes it possible to switch controls, it can add some more flying controls (like climbing/descending with your mouse wheel — these are really invaluable for people like me who play on laptop keyboards that have the traditional "flying keys" all over the place) and it can even add mouselook.
