I'd like to see another Wizards and Warriors game, but with better controls.
But what I'd *really* like to see is another Shatterhand game. Just a one-off Jaleco platformer. Except you wear sunglasses and beat up robots with your cyborg fists. You punch bullets. It's so badass. WP says it was based on a Japanese TV show, I wonder if they'd be afraid to revive it since in the Japanese market it was based on an existing character.
The music is great, the graphics are great. Like Ninja Gaiden, but no cutscenes, and a little shorter.
