Nice, everybody is waiting for this for many years ! But when I saw it's a relic entertainment game (I really don't like Company of Heroes, it's the casual RTS par excellence) I am not confident.
AoEO was actually pretty nice and improved on some of the aspects that made AoE 2 kinda awkward at times. It just died because GFWL died, the game itself was pretty good and i enjoyed it.
I already know about celeste, i just merely wanted to point out that AoE 2 wasnt the only game that they made that was good.
