I'm just keeping my doubles and posting them on Craigslist with a list of the discs I don't have. I made one trade last night, I went to trade the girl my Pieces of Eight for the TRU exclusive disc and she ended up giving me 3 more on top of that which I didn't already have.
I wasn't going to buy initially, but after seeing all the reduced prices today, I went for it.
Got the starter pack/heroes pack/villains pack/cars playset/6 power disc packs all for about $130. The game is pretty damn cool too, heading back tomorrow to see if I can pick up the Lone Ranger...
I'm not sure I'll bite at that price for those games, yet if it was double the price and included all the console Zelda games, I'd already have it preordered
Gtr2 is 3.60 as well but if you buy them make sure you go to no grip racing and download the patch and nocd files for Gtr2 as the steam version had to remove the porsches and Ferraris due to licensing issues. Those files put them back.
