I know there are lots of old school games out there, with more game-play than most of the new ones, they just need to be re-made right.
Here are some I can think of, off the top of my head:
WAR, INC. (your a mercenary company.. includes stock investing, cloning troops, building an army that came with you from mission to mission, maybe the addition of a conquest map)
DOMINUS (just full of awesome features.. it is just a couple things short of being one of the most awesome strategy games ever)
CASTLES! (an old castle building sim that took weeks of my life)
BTW, I think most of these are abandonware.. soo you can download them free and play with dosbox. just to get an idea of what they are. I still like them even with the dated graphics.
Anyone else have any great old games that need to be redone that I am missing?
