You could try Voodoo Vince.
I'm near the end (I think) of it and it's nothing Earth-shattering, but not a bad game if you can find it cheap.
Some of the jumping sections can be pretty frustrating and the controls feel kind of clunky until you get the timing of the double jump down. (Wait too long and Vince kind of sighs and won't double, do it too early and you don't get the height or distance you sometimes need, but after playing for a bit the timing becomes natural.)
And the game has a tendency to have you jumping from platfrom to platform over a bottomless pit or water, so if you miss you die instantly. You also have to remember to float or it is near impossible to land on some of the smaller targets, as you can't really tell exactly what you are over without floating.
And some of the character models are just pretty bad looking. Especially for a game that is a 1st party effort exclusive to the Xbox.
But looking past that, the game is really pretty good. There is some pretty good humor in the cut scenes, and a few of the puzzles are pretty neat. Although some of the puzzles have the feeling of you just hunting all over the level until you come across an item you can pick up and then you simply carry it to where it is used. Simple find and fetch stuff.
If you can find it at Best Buy it should be $10, I'd snap it up at that price.
Oh and yeah BG+E is a great game, while it lasts. I'd imagine you've completed it by now unless you haven't had much time to game in the past couple days. Voodoo Vince seems like it's going to end up being about the same length (though not as good of a game)
