Several things come to mind:
* Imagine if someone posted a comment on here before KZ2 was released on here that said something like this. I am sure the user would go gotten flagged for trolling, and being too negative. The belief that someone would have this comment regarding KZ2 wasn't even on the radar of the supporters of the hype bandwagon for the game.
* Exactly how is 3 million in sales bad? That seems good to me. One expects it to end up doing Halo numbers? Anyhow, not sure where he got 3 million from though. It is currently at around 2.2 million on here. Being an exclusive is no lock for it supposedly selling like a monster. One thing, multiplatform games will tend to get more advertising.
* Doesn't Call of Duty run at 60 FPS? Killzone 2 runs at 30, the way Bad Company does. Because both games try to do more with the game physics, they will likely run slower, and your aiming will also be slower than in Call of Duty, which has a less complex engine and runs at 60 FPS.
* Also, the last I played KZ2, it didn't feature aim assist, so you were forced to be precise with your aiming, and slower aiming helps with that.
Anyhow, I did praise KZ2 when it came out, and still will praise it now, for what it is. I will say that Bad Company 2's engine is pretty up there too. Wow, talk about a nice bunch of things going boom!
