I'm going to EB games tomorrow, but I don't know what to trade in. GTA: IV or GTA: EFLC. I don't want to trade in EFLC, then completely regret it when I walk out. Also, when I do trade a game in tomorrow, I have a choice of buying Killzone 2, or Uncharted: Among Thieves. I don't have online, so if I pass Uncharted, I can't free roam. Any recommendations. Btw, Kz2 is about 30 odd dollars, and Uncharted is nearly 40. EB Games are having a 50% off sale for pre owned, so I thought I might pounce at the oppurtunity.

Recommendations, please :)

I own both, but if I were you i'd get KZ2. Besides the campaign, you can play offline with Bots.
