just got a ps3 this weekend (<$300 used with ff13 and nccafb2012)... i think i will spend the next 2 years soaking up all the ps3 games i never played (used they are practically free!).
by then the ps4 will be a year old with plenty of titles and hopefully all the initial hype/bugs are gone
also, did u know that gamestop offers full refunds on used games (within 1 week of purchase). so if you beat it within a week you can return it and it's on them!
