My advice is this. Go over to cheapassgamer.com, register, and go to the Trades forum. The site is reliable and the users all have ratings on them for their trades and feedback. Offer up what you have to trade, and people will send you private messages with what they're offering. You'll have to go first since you're a new user, but you can look at the individuals' ratings and see if you want to trade with them or not. This is probably the best way to not get scammed.
Seriously, don't do any trading here with people you don't know because there's no feedback ratings. Just go over there and do it. That site is built around finding good deals on games and doing tons of trades between community members, so you're much better off trying to trade there than here.
Invading world of the guilty as spirit of vengeance The guilty pay the price. I hate Square-Activision's FFXIII and its slew of cash-in spin-offs & sequels
