Mega Man 9 & 10 (though, you already have 9, right?)
LostWinds (there's also a second game, Winter in Melodias, I think it's called).
There's the 5 Strong Bad games, if you care for Homestar Runner & Strong Bad, or point-and-click games in general; if you're not familiar with the franchise, you might not find it as endearing, though...
Final Fantasy Crystal Chronicles ~ My Life As King
Final Fantasy Crystal Chronicles ~ My Life As Dark Lord (especially recommend this one; think of a cross between Disgaea - for the zany comedy - and Grim Grimoire - for the RTS gameplay and medieval fantasy theme).
Eduardo Samurai Toaster - a platform shooter along the lines of Contra, humor along the lines of Earthworm Jim; short game, might keep you occupied for an hour-and-a-half, but it's a nice atmospheric experience, and if you're just looking for something to help you rewind at the end of the day, you can complete it in one sitting).
I think that about seals it up, if you're looking for familiar stuff by major companies
