[Suicide Junkie]

You know, that gives me an idea for the Humans- Only Version.

I could add a tech area "!Speed-Turbo", and one called "!Speed-Medium".

They would be disablable by the person creating the game, and the best available one would trump the others.

Slow would be say -2 speed on all engines currently in the game.
Medium is normal.
Turbo could double engine speeds.

Instant speed options, and only one mod to download!
