This is one of the greatest games of all time (GOAT), but you really need to play it with the HD Mod and HotA updates. There is an active community developing both. I think you just use them with this purchased install folder. HotA allows an active server for multiplayer games and simultaneous turns (until humans fight the first time in the scenario). The HD Mod allows several resolution options that let you make use of greater screen space than people had in 1999. I'm actually hoping to create my own turn-based strategy game for mobile, largely from being inspired by this game. It's that good.
It has everything. If you like RPGs (not the leveling up & chase gear sort, but the story driven) or exploration, this game is for you. It's better than Dragon Age, that's for sure. Simple to play, yet almost unbelievably deep. This game has action (Arcade Asteroids style), character development, & exploration. But the graphics weren't even good in '92.
