Hi, I have 6 games and I like every one of them. I want Left 4 Dead so much but I don't work anymore so I have to trade one of my games for L4D. Here's the list of my games ...

- Gears of War 2

- Fable 2

- Dead Space

- Tales of Vesperia

- Halo 3

- Soulcalibur IV

I don't know which one I should trade because they're all awesome but I haven't finished them completely so I don't know what's the replay value of each one. If you have those games, which one has the most replay value and should be kept ? Thanks :)
