Maybe it's just me, but I'd rather sit down and relax if all I had to do was point at the screen. I haven't been able to get my hands on MP3 yet, so I wouldn't know for sure.
Sadly, I've finished both MP1(75%) and MP2(86%) already, so all I have to entertain me now is the original Metroid, and I don't think I'll ever be able to get any farther than that. Of course, there's Paper Mario, but I feel no urge to try and figure out a strategy to kill the over-powered last boss.
