I'd recommend Commando, which is a pretty good game aside from the annoying flicker. Shadowgate isn't too bad. If you like baseball games, you'd want to try RBI Baseball 2, which is the best in the NES series. Fun little arcade-style baseball game. If you like a challenging game, Tengen's Vindicators is a good one. You pilot a tank through stage after stage of enemies. Jackal is an arcade-style game which can be played alone or with a friend (co-op).
