I've been playing L4D2 and Champions Online like it's my 4th job (I have 3 jobs) and they're both great games.
Warcraft 3 + Frozen Throne + Dota Map = The most time I've spent on any game ever. I must have played some 10000+ matches on Dota over years.
Actually, the more I think about it, it's probably way more than 10000. Mmmm Dota.
Edit: On Champions Online, MMORPG with cool customization. There are no classes, you can choose powers from some 20 powersets and mix and match all you want, and the costume creation is a blast. Great part too, most MMOs suffer from a high amount of downtime (read as walking/travelling time). This isn't the case in CO, you can get from one side of the map to the other in a few minutes once you get a good travel power.
I remember playing WoW and it would take a few hours of play to get anywhere. I can log onto CO, play for 20 minutes, and finish like 5 quests, it's awesome.
