Darkwing Duck and Talespin are decent games, which are only seen as terrible because the NES got all of those great Capcom licensed Disney games (imagine a TG16 Ducktales... drool). Yo Bro! is a good game, and to me, seems like it could be on a few top 10 best TG16 games, so I am surprised it got a vote. Falcon sucks, but I think it is because I don't like the flight sim genre, and not necessarily because it is a bad game.
Timeball is just no fun to play, it is terrible. That's why it is my pick. Sorry to hear about your Christmas djolof, but Boxy Boy is somewhat redeeming at least.
