well, if you check out arcadepod.com, you can find Mario-related games such as "Masao" which is like Mario Bros., and "Chucky Eggy" which is similar to Donkey Kong. Also I have a game on my old old computer known as Crystal Caves. It has about 1000 Mario references in it! (exaggerated) for instance: Mushrooms, warp pipes, hidden blocks, etc. Does anybody else own it?
