I did get a Wii for its exclusive titles. I had an N64 and a SNES before that. I like Nintendo.
I also have a PS2 where I played GH, GH2 and GH80s.
When GH and RB came to the Wii, I could have bought another console just for those or use the one I already had, which is what I did. Considering GH git its start on the PS2 I figured the Wii wiukd be able to handle it. For the most part it has.
