Yeah I played the Bioshock demo and it was great.
Although I dont really look to the 360 for RPGs.
Id stick with the Wii/PS3/DS/PSP for them.
But one title I'm really looking out for is Banjo Kazooie 3.
And yeah, PS2 was really good as well.
Id say that PS2, SNES, N64, Gamecube, and GBA were some of the more memorable platforms...
