Dr. Boogie, you've written that already, just go read someone else's reviews or thoughts on it if you think my thoughts are non-trustworthy.
Zomboid:
http://www.metacritic.com/games/platforms/ps3/resistance2?q=resistance%202 , thats a 87 Metascore on Resistance 2, great score i'd say.
Now let's look at Killzone 2:
http://www.metacritic.com/games/platforms/ps3/killzone2 91 Metascore, now i know you'll scroll all the way down past the 100's and 95 reviews and look straight at those three 70 reviews but seriously, not mixed.
Really, if you want to argue why i think the ps3 is better in games and hardware and features, etc, i can do it quite easily
