YOU THINK konami would know better, after the casual dewys adventure was a monsterous flop that probably lost them a ton of money. Elebits got lucky it was a launch title. Hardcore games do just as good on the wii, as long as they are properly marketed. I go into a gamestop and I see the (casual people) playing the metroid prime 3.
When people think casual you think of ur soccer mom, ur grandma, etc... they truley make up a fraction of the wii population, I for a fact dont know anyone besides hardcore gamers (around 5-6 guys) who own a wii, no mommys here. I know they are out there but they are truley a tiny fraction. There is no such thing as a casual system, people buy what's marketed to them.
