Original Message: I like MM9 not because of their graphics ,but just for having slightly
different approaches ,comparing to MM6-8 .
Combat is a bit different .
Then class advancement -
1) Back to MM 6-7 : two promotions for character !
2) You have choice , for example choose mercenary or gladiator
etc !
3) You can't complete promotional quests for classes you don't have .
All in all MM6-8 looks good for me but sometimes you want play somewhat different might and magic to refresh your mind
