Ogre Battle would make a great touch game. I have to say, though, the game is freaking hard. It wasn't til just the last couple years that I got a decent handle on how to play it (after failing miserably as a child), and that required a lot of guide reading. Rule #1 is every unit must be flying. MUST BE FLYING. I still haven't beaten it since I bought it on my friend's Wii and beating a level takes like 3--4 hours. He moved away and now has a baby so it doesn't look like I'll be finishing it anytime soon.
