Little Nemo: The Dream Master is a great game but very tough.

Snake Rattle and Roll was also hella fun (for the first few stages), but was never able to beat it without cheats.

Star Wars and Empire Strikes Back, great games but tough as hell too.

Out of your list I only played Star Wars and Empire Strikes Back, the latter of which was really cool considering all the Force powers you could use. Plus I remember that when you dies but didn't continue, Yoda would say "And that is why you Fail!" lol.  I beat both, which were good games and really tough.
