For his age (which is pretty much Peter's age) I think the Wii games are still the best. Our old Wii no longer reads disks so rather than replace it, Peter will be getting a Wii U for Christmas. It can use the legacy Wii controllers and games. The older games don't fully use the new platform but I don't see that as a fatal flaw. Peter also loves Little Big Planet and Little Big Planet 2. Both of those are currently only available on the PS3. Take all this with a grain of salt as I am a staunch non-gamer.
