[quote name='SynGamer']My PC can't handle Portal 2...has anyone been able to trade/sell their PC code? I'm not really sure what to ask for it. Successful sellers advice appreciated. That said, the game is great. Loving the humor just as much as the original. I'm currently stuck on Chapter 3, but I refuse to use any guides.[/QUOTE]
Considering that you initially need the PS3 copy and a PS3 with access to PSN, you probably can't get too much for it. I'd say $20 at most, since its been down to $30 retail recently. Better sell it quick, though. There will likely be a Steam summer sale in the next month or two, and there's a good chance Portal 2 will be featured.
