So I think I want to buy a game today. What should I get

[Kantor]

You don't have MGS4.
GO GET MGS4!!!

Seriously, your PS3 library is extremely lacking. You don't have any of the system's best games

Start off with mgs4

Then get Oblivion

Then COD4

Ninja Gaiden Sigma

and whatever else you think looks good. You have pretty much all of the Wii's best games so leave Wii shopping to the side for now.

Also, ignore the troll post above me, selling consoles is a BAD idea.

EDIT: Just for the hell of it, I'll go through the games he mentioned

sell all your games for ps3 and wii and sell both consoles and then buy yourself the greatest system this gen...The xbox 360 then get Rock band, Guitar hero 3, halo 3, gears, ninja gaiden 2, forza 2, mass effect, call of duty 4, and anything else that looks good. ; )

Rock Band, Guitar Hero 3 and COD4 are all on PS3.

Forza 2 is an attempt at Gran Turismo. GT5 is coming out next year.

Ninja Gaiden 2- Sigma is better and a PS3 exclusive.

That leaves Halo 3, Gears of War and Mass Effect.

If you haven't played Halo 1 and 2, there is honestly no point in getting 3 unless you already have the Xbox 360. Which you don't.

Gears of War is an excellent game. So is MGS4.

Mass Effect is very good. So is Ratchet and Clank: TOD.
