If you have any NES love in your heart, don't even watch the trailer. Just play it. Right now.
There are truck-loads of tribute/parody/mash-up NES games floating around out there on the internet, and some of them are really fun, but if I had to choose one game to sum up the NES, to pay ultimate tribute to 8-bit, then it is without question Abobo's Big Adventure. This game is more NES than the NES.
