My biggest lament with the PS3 is the forward incompatibility making many great games locked to the platform (MGS4, Demon’s Souls, etc.). Meanwhile in Xbox land there are *633* 360 games you can play on any new Xbox by just slipping the disc in. Now some of this is no doubt due to differing approaches to business by the corporate masters but from what I’ve read a lot of it is the unique and befuddling architecture of the PS3.
