I believe Shape Shifter is US only as well and that's a fine game (if difficult).
Nope, Shape Shifter came out in Japan.
Fair enough. I suppose taking 3 seconds to go to the PC Engine Bible site would have told me that. For some reason I was under the impression it was US developed and no US developed titles were released in Japan. I'm probably wrong on both of those though.
As for the Disney games, don't get me wrong, they aren't great games. I just wouldn't say they are some of (or the very) worst games on the system. I find them somewhat charming and I have to admit I was a big fan of both shows growing up. I'd rather play either than Falcon, Ballistix, any of the TV Sports games, Gunboat, Andre Panza Kickboxing, Battle Royale, Timeball, Power Golf and probably half a dozen other games I can't think of right now.
