The only really turn-based strategy game I've played is Snails. I like Real-time better for like flat games (ones that aren't "cannon-fodder"-type games), but I guess I'm not really an expert in the field, am I?
Anyways, I generally like real-time better, but Snails is a great game, Randall (one of the best, if not the best, PPC-original games out now).
