What should i get first?!

I was thinking about Lost planet i tried the demo online it was really fun that u play with friends and try to get to the top,i played the story on the xbox but i wanna get it for the online, but on the other hand i was thinking about folklore is it a good game to get first or what guys am confused about both? :S

Dont get Lost Planet, really bad port.

I haven't tried Folklore, but I do have Ratchet & Clank, totally awsome game! Burnout also has a great singleplayer & multiplayer. Uncharted is probably the best single player action/adventure game out for the PS3 right now. If you like shooters, R6V2 is coming out in a week or so, maybe it'd be worth buying. I haven't played COD4 though.
