If you want something to play with him, Ghost Squad is only $30 and incredibly fun in co-op mode. So is RE:UC, for that matter. Both are basically, "point at the screen, shoot at stuff," so they shouldn't be too hard.
Also, do you have Super Mario Galaxy yet? For co-op, you could control Mario while he plays as the second player.
"'Casual games' are something the 'Game Industry' invented to explain away the Wii success instead of actually listening or looking at what Nintendo did. There is no 'casual strategy' from Nintendo. 'Accessible strategy', yes, but ‘casual gamers’ is just the 'Game Industry''s polite way of saying what they feel: 'retarded gamers'."
