I just found out that my local GS has a lot of copy of Rez BUT for $40(NEW). It had saled copy of Culdcept too but for $50 and you can get them online for $40 and eb has it used for $12.
I wouldn't pay more than $30 for Rez. I thought the game was ok but I don''t understand why it is so sought after. I paid $26.50 for it after shipping and tax from BestBuy.com 2 years ago.
i wish i could get it for $20 shipped from someone that got an extra copy from the TRU sale..i'm going to have a chance to play it on DC and i heard that it is much much better than the ps2 versio
