So to whom people think I am some fanboy...both are terrible. I really want to see next gen scores now. I can see why people are mad about BF4, a next gen game releasing on old gen consoles is rough. However, the PC version seems to be a hit or miss - and people with dual core cpus probably never will be able to play. I just hit ~26 hours last night, rank 21 (almost 22). Last night had some bad lag on 1 server, then the next game was completely lag free. Crazy.

With these scores, looks like Killzone is a good choice for next-gen FPS for PS4 buyers.
