Replace Guild Wars with Quake 4 or Call of Duty 2.
I have:
WoW
All the CS games
All the Half-Life games
COD2
Quake 4
WoW
FarCry
And some others, but I only really play COD2, Quake 4, All the CS games, and WoW. If you get WoW and you are planning on keeping it for a while, you'll need about 80 bucks for the 6 month subscription.... But the CS games are the next best thing. Get Source and Anthlogies, those together come with CZero, Source, CS 1.6, DOD:S. Oh yea, COD2 is pretty fun but you'll mostly be playing the CS games and WoW. Quake 4 > COD2m IMO. The online action is way more fun and yea, it has better graphics that any of the other games, and I can run them all on high so I know on my computer Quake 4 has way better graphics, next would be, IMO Source, then COD2.
