Longest lasting ps3 game?

I want the best and longest lasting ps3 game from below (I want the longest)

Final Fantasy 13

GTA4

MGS4

Resistance 1+2 (No, I won't play multiplayer, too busy with MW2, Uncharted 2 and Fat Princess, yes, Fat Princess)

Fallout 3 GOTY (that is with all the expansions)

Dragon Age Origins

Mass Effect 2 (it's on the ps3 in Feb)

I am thinking of getting Final Fantasy 13, and as a "fan of linear games" I don't care about that stuff. Any suggestions for longer games? Also, I get to buy 4 games at around the holidays, planning on buying Other M, Mario Galaxy 2, Black Ops, and depending on what I buy now, Versus 13, Mass Effect 2, Gran Tursimo 5, or Fallout New Vegas, any thoughts or suggestions?

I've probably logged more than 100 hours total into Fallout 3 GOTY in about 2-3 months. I was doing all of the side quests and some unmarked quests. I had over 100 hours and I didn't even finish all of the DLC and sidequests before my disc broke.

I don't really think Fallout 3 GOTY is for me because on the PS3 it crashes too much

Sacred 2. People still play online. You can pop n out anytime in multi. World is huge. You will spend hundreds of hours playing this game. currently i'm over 2,000 hrs.
