What game should i buy for ps3?

Theres MAG, black ops is coming out in november, killzone 2 but killzone 3 is coming out sometime this winter probably jan. Red dead redemption is fun but its 3rd person. uncharted 2 is a great game but it is also 3rd person. Other fps are battlefield bad company 2 which is probably the 2nd most popular besides mw2 and medal of honor is coming out this fall which looks like a mix of bc2 and mw2. Resistance 1 & 2 are both good but im not sure how many people still play that.
