Xbox have just somewhat copied the PlayStation Plus free games giveaway btw (confirmed extension of their Live free games offer that they ran before). Sony have some good ideas.
It's funny because Nintendo need to copy what Sony (and MS) are doing in so many aspects (particularly online/OS/3rd party relations). Yet people here see copying as some sort of a bad thing, snubbing Sony over taking popular ideas and implementing them.
It's adapt or die, and with the Wii U it sure seems more like the latter these days.
