heroes of might and magic 3
An absolutely AMAZING game for computers, with replay value that kicks that of the popular Xbox game Halo even though it was released three years earlier and is a sixth-person view game that runs in its own DOS shell, and it doesn't really measure up, graphics wise. You have the opportunity to customize virtually every aspect of the game, and this power is only enhanced with add-ins like WoG and Modhomm3. This is a phenomenal game that has kept me entertained since the day I bought it and you should also get it. Produced by 3DO.
I have beaten all of the scenarios and campaigns on "Impossible" difficulty, including all the 94 that I made. I needed a new challenge so I downloaded about 200 more. This is going to take a while.
