"Halo 4 (estimated LT sales based on a secret formula): 10.9m"
LOL! I'm sure many people would love that, including Microsoft. I don't see it selling that much unless its bundled.
Anyway I think you're wrong. Quality DOES equal sales. What you are missing is that there are a lot of factors involved in determining "quality". Reviews don't always do the best job of this. Marketing is a big part of it. If a game is of good quality but no one knows about it, it won't sell. Simple as that.
I was about to point out that that the Killzone franchise is growing with each release, but I'm wrong. Sales for KZ3 don't look to ever surpass Killzone 2....so what is the problem here? I think Killzone IP isn't appealing to the PS3 FPS crowd. Speaking for myself, I played the multiplayer beta, but it wasn't anything special.....for the single player demo, I even got stuck lmfao.
