Yeah, I pretty much play them all when I feel like. However, Dungeon Siege is terrible and I got it free with a video card, Quake 4 I got with my 7800GT and it is awesome, the Valve games all came in one package, I'm borrowing Chronicles of Riddick (which is also awesome) from my friend as well as Fable, I received A.V.P. 2 from my friend for my birthday, ePSXe is an emulator, and Halo was also given to me.
So, really, I haven't bought many of them. I haven't even played Counter-Strike online with other people yet
, but I've beaten Half-Life 2. Still working on Quake 4, and Far Cry is on the backburner for now because I'm stuck. GuildWars hasn't seen much action as of late because I'm in a really annoying situation and I don't want to start a new character right now. I actively play U.T. 2004 online and offline, Quake 4 just offline for now until I'm better at it. I'm stuck in Republic Commando and it is really frustrating, I just CANNOT get past this one part. I've beaten Project: Snowblind twice and I'm on the third go-around, but I just haven't played it lately.
