Vice: Project Doom: I dont remember many people talking about this when mentioning top NES games. This game is freakin awesome, IMO, with Spy Hunter style shmup stages and side scrolling stuff. It all controlled wonderfully and well, it had parallax scrolling backgrounds!

Traysia: fairly good Genesis RPG no doubt pissed on by gamers who only played it for 20 minutes. Despite the shit graphics, even for Genesis, it's quite good IMO, just give it time. Great music a decent cutscenes too.
Astal: I find this a shining example of good 2D, despite the pixelization with some of the scaling. It was a bit kiddy and easy but it was a fun platformer IMO. Excellent music also.
