I will most likely get one eventually for games like Ni No Kuni, Graces F, Wipeout HD Fury, Katamari Forever, Ridge Racer 7, etc.
As to what could get me to buy one RIGHT NOW? It'd probably have to be Ganbare Goemon or Choro Q, both of which appear to be dead, so I don't think there's anything that could do it. --- http://terosclassicgaming.blogspot.com/ - Watch me beat "SNES Aladdin" http://www.backloggery.com/tero - My backloggery
It was MGS4, luckily I ended up getting a lot of better games that made purchasing a PS3 worth it. --- I am a dedicated member of the "Walter Sullivan Is Bad-Ass" group!!! I am the true originator of the Cookie Demon theory on the SH2 and 3 boards.
