argh, I posted a long reply but my comp timed out before I could post it. but the gist of it was:

@Raccoon Lad: I thought FZ on GG was a blast, the scrolling didn't bother me much, and I played this version before I knew the story modes on the SMS versions existed, so I didn't miss them.

@Six Switch: Gunstar for GG is Japanese only, I had an opportunity to try it out once. It is the same game, with bigger sprites and less onscreen action simultaneously. But it was still pretty cool.

Finally, Alladin for GG follows the movie EXACTLY. Better than the Genesis version, much better than the SNES version. It even has dialogue directly taken from the movie, and in game cinema scenes that help the storyline progress. In short, it's like playing a side-scrolling, 8-bit version of the movie.
