OK, time to get this started for the classic discussions forum. Let's start building a list that others can use as a guide - even if your suggestions don't make the list, at least your suggestions get seen! These threads should be especially handy to people who got their systems recently and want to start out with the "A List" of games to pick from.
So let's start the "A List". What would you add to it?
NOTE: * = exclusive to this system (for now)
Metroid Prime 3 *
Super Mario Galaxy *
Super Paper Mario *
Wii Play *
Wii Sports *
Zack and Wiki *
Legend of Zelda: Twilight Princess *
