I don't have the GC anymore, but I reckon I have racked up a good 100hours of Gamecube gaming since I bought the Wii... almost half will be on Eternal Darkness because I only bought it 3 weeks ago.
Of the remaining time (approx 60 hours) most will beon wave race or burnout2.... and some F-Zero GX.
I just want 1 great, non-arcade racer to come out for Wii and I'm set. Mario Kart will help but I won't be satisfyed until F-Zero Wii, unless Ferrari Challenge turns out great (doubtful)
There is a damn good reason Europe is the Wiis weakest market compared to PS3... no great racers (I am pining for some quality F1 action and having to set up my N64 to do so is annoying)
I think that Sony still exclusively owns the F1 licence and even EA stopped to make yearly F1 games because their games didn't sell that well without the drivers/teams of the current season. So if you want an F1 game on Wii, you are out of luck.
Now if only Codemasters would use the oppurtunity to bring their racing series (Rally and Race Driver) to the Wii, that would be awesome. But alas, certain 3rd parties just don't seem to understand what to release for the Wii, even though they would have a niche to fill all of their own.
