what good rpg's for 360 should i get? (fps games too)

I just got a 360 and I was wondering what games to get. I have been waiting for last remnant for a long time, but it got really bad reviews. I was wondering if I should get last remnant or oblivion to start (I want my first game to be an rpg). If u have any recommendations for any other rpg's please tell me.

I also want to get really good first person shooter, any ones in perticular i should get?:question:

Edit: Please make sure that you use the Game Recommendation Thread for all questions about what game to get. A message from the mods.

RPG

1. Fallout 3 - best game ever

2. The Elder Scorlls 4: Oblvion - just got it, pretty fun

3. Fable 2 - it got good reviews

FPS

1. Halo 3

2. Battlefield: Bad Company - great multiplayer

3. Left 4 Dead

WRPG: Fallout 3, Mass Effect, Oblivion, Fable 2

JRPG: Tales of Vesperia, Lost Odyssey

Lost odyssey is pretty good if you like turn based games.

Fallout 3 is really good if you can get into it.

Mass Effect should be pretty cheap now and is an outstanding game.

I'd Suggest Fable 2 For RPG's

And I Call Of Duty 4 Modern warfare for Fps's
Both Outstading GAmes Hopefully Youll Love em :D
