Been playing this game a few hours now and really liking it. It completely reminds me of playing my NES back in the late 80's. there are soo many references to things, its almost impossible to keep up with it all.
Also, I really like the video filters the game has, you can make the game look like its being played on a gameboy, a NES, a Megadrive or a Virtual boy if you want, to name just a few. You can even change the borders of the game to look like its being played on a arcade cabinet and other crazy stuff like that
