I think you should reconsider axing Tales of Symphonia. It's my personal favorite gamecube game. A really solid long RPG.
I also say Axe Animal Crossing if you plan on getting the Wii version. Animal Crossing is a great game but there are very few changes between GC, DS, and Wii so you really only need one version. Gamecube has NES games Wii has a few more things around town, but not a ton.
