Contra (and its sequel Super C) and Battletoads. Many of the sports games like Tecmo Super Bowl and Blades of Steel are really fun in multiplayer too. Those are the ones I can think of off the top of my head.Single Player games: Super Mario Bros 1-3, Zelda 1-2, Punch Out, Kid Icarus, Mega Man 1-6, Ninja Gaiden, River City Ransom, Metroid, and Castlevania.nes multiplayer games?
Definitely TMNT 2 and 3. Some of the best beat em ups on the system.
TMNT, super bombman, bubble bobble, knights of the round.
