Games that consumed a large amount of time for me during WoW's lifespan:
Battlefield 1942 (friends and I played that game up until well past BF2's release)
Skyrim (for all of ~400 hours total, 2 complete playthroughs)
SWTOR (for about a month real time, realized it was a wow clone, said to hell with it)
GW2 (now at about 1500 total hours played)
For perspective, I have about 10 times as much time on WoW as I have GW2.
