neverending games

In Games

..Games like Duckhunt and Spy Hunter (?) that just keep going forever.
Is there a list out there of NES Games that never end? If not, let's start one.

Kung Fu
Galaga (I think)

Tetris won't end I guess...

I'm not sure, so don't take my word for it, but:

- PacMan (Mrs. PacMan).

- Urban Challenge.

- Pinbot (or any kind of Pinball game).

Berzerk, Space Invaders, Asteroids, Mario Brothers, Galaga, Simon (if you wanna call that a videogame)

too bad most of those aren't NES Games.

Tetris won't end I guess...

Unless you max the score!
