I think defend your honor is the best strategy game It's not too much action (sorry girls don't like that ) and it's funny! It looks good, the conversations are really funny, i just like it
I'd say it's Civilizations Wars. The game is very easy to learn, yet requires a lot of strategy, whether you're predicting your opponent's next move, choosing the proper combination of skills for the next battle or simply finding a way of getting those other guys off your turf ASAP. What the game sorely lacks is a multiplayer mode, though... Colony has a major advantage there...
Both Warfare 1917 and 1944, great games could be made to be a little more challenging and needs to be muliplayer that would be great but really great games I love them.
