Bonk's Revenge for the TG16 was the really good one, definitely better than any other Bonk they made for any system imo. I do quite enjoy the combo Sonic & Knuckles + Sonic 3 because you can pick whatever level you want to play, it was ahead of its time in that regard. Kirby's DL 2 on Gameboy is up there. Rescue Rangers on NES was fun, and I did like Donald Duck in Deep Duck Trouble on Game Gear. Mickey's Dangerous Chase was a favorite of mine because of its similarity to RR. A lot of people like the Castle of Illusion, Alex Kidd, I think Aladdin on Genesis would count too.
