I love AoE II, I used to play it all the time with my friends. It's probably my favourite video game.
AoM was pretty good, but kind of disappointing in that the myth units were useless- the best strategies involved only human soldiers. I also didn't like the expansion. The Atlanteans were a pain in the ass, and the titans were just lame.
I haven't played video games very much recently, though. I quit WoW a couple years ago because it was no longer as fun and took up too much time.
I did play Portal recently though, it is an excellent game, extraordinarily well made.
