Okay, this idea came to me just recently, and I've already started working on it.
Recreate a classic video game, but for graal use.
I'm currently working on a 1player version of Spacewar, the first computer game.
You have to script it (GS1 or GS2) and post the script (or a level it's in) along with any gfx you have made for it. I know competeitions fail in the past, but still, it would be pretty cool to see what we can come up with
If you don't like the idea, don't do it. But I think it could be a lot of fun.
