i need your opinion!!

i can get 2 games for my new PS3. one of the games is MGS4 the other is either street fighter4 or killzone2. i dont know witch one to get! i love COD4 gameplay and everything do you think i can get used to killzones slowness and what not. i feel like skipping killzone and wait for modern warfare 2. killzones lack of guns is bothering me. only 2 assault rifles that u cant even costimize....wat should i do

I say you should use the recommendation thread... but I'll aslo say SFIV.

killzone 2 gun aren't that good i say get SFIV

Valkyria Chronicles.
