Ok, my coworker just asked me this:
In the original release of the first wave of Nintendo games, which three titles had options within them that allowed you to create your own levels?

I know 1 is excitebike, anyone remember the other 2?

thanks

Ice Climber ?
or rather some demolition game.

Mach Rider and Demolition Crew.

Well, technically it was called Wrecking Crew, but you still deserve a cookie. That one I knew, but I had forgotten about Mach Rider.
