Sorry if this topic has been done before, but...
What are some of your favourite underrated NES games out there? I'm not talking about cult classics like River City Ransom that every NES fan knows about nowadays, but those gems that NOBODY seems to ever mention, but that you think are excellent games.
My pick: Clash At Demonhead, one of my favourite NES games of all time. It has lots of areas to explore (with a built in map), interesting characters, good story with various plot twists, hilarious dialogue, many different items and weapons, nice music, replayability, and multiple endings. And I think that the early style of anime-type graphics in this game have aged well. This should have been a smash hit, in my opinion. My tip for trying this game: if you can resist the urge to hit the power button in the first ten minutes, you'll be glad you did.
So, let's here about your closet classics for NES that deserve a another chance.
