@Bolded: What?!

Selnor, get LBP. Its by far one of the greatest exclusives on the PS3.

demon souls

I just put in a couple hours and It's excellent. It's too bad it's my aniversery and gotta get things ready or else I would be on all day!!
Its a great game if you like oblivion and I guess diablo type game you would like demon's souls

This is good guys. Most of these games I have heard about. Definately will be buying ( if I dont like I can trade it. :) )

Any obscure titles? Titles not normally talked about?

dont get LittleBigPlanet??? 

100% GET LITTLEBIGPLANET!!! One of the most creative and fun game's off all time, so original and is fun to play alone, online, with friends and family! if there is 1 game in the hole PS3 library u should get it is defo LittleBigPlanet

also try:

Killzone 2

Uncharted 1, 2

Infamous

MGS4

Heavenly Sword

Motorstorm: Pasific Rift

and in the future God of War 3 & Gran Turismo 5

Don't get:
Resistance: FoM - Just buy R2
Valkyria Chronicles - If you don't like SRPGs a little
GT5:P - I think you know why

MGS4 and Valkyrie are musts. MGS4 is probably my favorite game of all time, and Valkyrie made me LOVE a game in a genre I otherwise hate.

inFamous is a ton of fun. Not the deepest game, just lots of fun.

KZ2 is great...especially online.

Those 4 should be a good start.

I wouldn't trade any games, the value you get is too low. sell it on ebay you deff get value there. I hear trine is really good. It is a psn game that is suppose to be really fun
