If you think you can find 6 complete (if they're not complete EB may refuse them) qualifing games at Rogers, then yeah it's not a bad deal. I've been playing the PSP I got with the Trade 8 deal quite a bit, it's a nice system with some great games. Just make sure you look at the PSP you're getting before you seal the deal, if it's beatup it's not worth the hassle.
Oh also, it is quite possible to find qualifing games for
