Age of Empires IV. Man, I've really missed being able to play a good traditional RTS. And AOE IV is pretty good. So far it feels much closer to AOE I and II than it does to the rather disappointing AOE III. Thank goodness.
I'm hoping they add more cultures as the current roster seems a bit limited. One thing I wouldn't mind seeing again is the game mode that has you building a city outside of the RTS gameplay. Not sure it would really fit, however, since that city represented the old world sending meta progression things to their colony in the new world. But, that was perhaps the only thing about AOE III that I really liked.
Anyway. If you like traditional style RTS games, I can so far heartily recommend AOE IV.
