Valve is the only company widely successful in the PC gaming realm? Bioware (KOTOR), EA (C&C and The Sims), Blizzard (WoW), Lucas Arts (Empire at War), 2K (Civilization), THQ (Company of Heroes), and Vivendi (more games than I want to write) all say hi. I can't think of anyone who's put serious effort into PC development who's been shafted by it recently. Maybe Activision with Quake Wars, but it wasn't that good a game anyway, and the Quake franchise is pretty much dead.

COD4 came out at the same time as Crysis so that will affect crysis's sales.

I REALLY want a good space fighter sim. An X-Wing vs TIE Fighter-like multiplayer game...it used to be a huge craze...now FPSs have taken over.

Perhaps when people get sick of FPSs, flying games could make a comeback.

 I was meaninig within the last year or two. Civ 4 is said to be slowest selliing of the series. Company of Heroes is an ok game out of the bunch. The Sims is selling nearly at a rate of Half-Life. C&C3 = failure (I have 300 people on my friends list on xfire and triple that on the friends of friends list, I barely see C&C3 played at all). COD4 is the most popular. WoW is hold strong but sign-ups seem to have slowen as they have 9.3 million members and thas not growing much at all. I though it would be around 9.5m by now but its not. KOTOR and KOTOR2 are a few years old now. Quake Wars = flop. Empire at war is played rarely but I see half-life: deathmatch classic more often. 

The problem is that PC gaming has gone so far with it's graphics that people are sick of having to upgrade ever 2 - 3 years so they just buy cheap computers that can run old classic games they already own and not move forwards unless they need to like to move to Vista or run COD4 on the lowest setting.  

Honestly I can't really bring myself to care about the PC gaming front right now what with consoles dropping megahits like candy from a parade float. When StarCraft 2 hits [edit2:  or Spore, I forget which comes first] it will be the other way around.

[edit: Maybe others feel the same way?]

I hope Spore doesnt flop. That game will bring PC gaming back to life.

Unfortunately Spore is coming to consoles too...and I honestly do fear it'll get "dumbed down." We'll see.

Either way, it's going to share the glory with the consoles, so it's not gonna bring PC gaming back to life.

Oh come on ssj you got caught with your pants down and now you are just plain talking bullshit.

C&C3 is not a flop http://www.thesimexchange.com/stock.php?id=23 (Sim exchange data all based on official NPD sales)

Neither is Civ IV, which sold a huge 6 million copies, making it the BEST selling of the series http://pc.ign.com/objects/620/620513.html

WoW sales actually increased the last 3 months according to NPD. 9.3 million ACTIVE users is insane.

KOTOR is old, but it was the last game Bioware made for PC. Doesn't mean it wasn't successful.

Quake was a flop as I said, but the franchise is dying. The big games are getting big sales.  CoD4 is reportedly doing very well also.  I'm not worried about PC software at all. 

 ok... umm... 1.6m for a C&C is pathetic... wasnt Red Alert 2 like 5 - 6 million? even Generals was about 2 - 3?

 Civ 4.. ok I'm just going by the lack of people playing it on my lists that has about 1200 people on it total. 

 KOTOR I never said it flopped, just a few years old now and KOTOR2 was made by Bioware so your a bit off. I own both games. =]

I've been wondering this too, will FPSs ever die off?  I don't see how people still havn't gotten sick of 8 hour single player FPS with graphics to brag about but little to bring something new in terms of gameplay.  Because 90% of the games that get hyped up on PC are those. 

I mean, sure there are good titles worth playing but I'd like to see different types of games too with some innovation.  You know, a game that appriciates you playing this on PC(recent example:  Valve Orange Box)

I guess its hard to focus on PC only when Consoles is where the $ is made...
