Tempo is a very good game, very difficult at times but a real showcase for the 32X. I have frequently compared its graphical quality to that of Worms Armageddon. Spiderman has some nice graphics but I couldn't stand its gameplay and sold it over a decade ago. Chaotix is technically using the Genesis for the backgrounds, it just "looks" colorful.
I am going to be out of pocket a bunch today, doing the new years eve thing with family.
