I've compiled a list of all current and near future racing games for the Wii, so if anyone wants to go for collecting them all, good luck! there's nearly 50 of them already, so if you're just getting started like I am, you have a long way to go! luckily, most of them are only $20 apiece, but there's still tons of them!
