WTF?! I'm NOT buying a PS3 then. That's smurfing idiotic. I'll have to wait until the inevitable port to Wii. Or until the PS4 is out so I can buy a PS3 for $100 or something (like I did with my PS2, which I bought for Dawn of Mana, which, thankfully, came out after the PS3).
I think the difference is that 3D Dot Game Heroes is ripping off very, very early Zelda (basically just TLoZ and TLoZ:ALttP) and specifically the aspects that Nintendo seems to have abandoned. I know little about Dante's Inferno or GoW but I suspect the case is different.
