I'm having the same issue.  I can't connect my account with my Disney Account.  I keep getting an error message that my user name and password don't match.

I also cannot sign in to the Toy Box Share to download any of the additional Toy Boxes.  I'm not sure if this is a result of my Disney Account log in issue or not.

Capcom Vs. SNK 2 EO is pretty bad because the graphics aren't very good and the GC controller just isn't suited for fighting games. However, I got it for $10 new at Toys R Us, so I guess I can't complain.

I used to have Star Fox Adventures, which I traded because I thought it sucked.

I can't honestly say that I dislike any of the games I currently own. I traded away all the ones I didn't like. I really thought Star Fox Adventures was pretty darn bad, and while I loved the original Jedi Knight for the PC, the GC port of Jedi Outcast was terrible, so I traded that away too.

If I had to choose I'd say The Sims: Bustin' Out, using my wife's opinion. She bought it, but thinks it really stinks, but we've never traded it for whatever reason. I agree that Super Mario Sunshine is pretty disappointing, but it has a lot of fun moments, and I do pull it out to play a few levels every once in a while.
