I ask this because I really want to try and get my head around this.
1. The treatment of PC as a platform was abysmal, offering no dedicated server support (multiplayer standard for the PC) and replacing it with an inferior option. Also, openly stating they don't want modding on their game (another staple of PC gaming).
2. Sort singleplayer campaign. Many people preffer SP over MP and this game fails to deliver for them.
3. Derivative FPS gameplay. I mean no offense, but if you started gaming this generation then I'm sure Halo 3 and MW2 seem awesome, just as Oblivion seems like the best RPG ever to people who started gaming around the time it came out. However, it has all been done before, much better and MW2 isn't particularly good in any way. It's mediocre at best, especially considering the resources it had.
4. Rampant hacking, even on consoles. Also, slow response time from devs in fixing all the exploits and hacks.
5. No Russian controversy. IW was trying to piss people off on purpose with this. On one hand, it's free publicity, but on the other it's also bad publicity.
Basically, an unspectacular game mired in controversy, focused on multiplayer, but with poor support for it.
