Great job man! For what it's worth I think it looks outstanding and I've had a space shuttle in my collection for over 25 years( also heavily modded). Cosmetically it's just pretty, I really like what you did with the pop bumpers and choice of colors with the LEDs. The 3D additions are nice as well, especially that Saturn V over the shooter Lane. Could you post a better photo of that planet hovering over the USA lanes?
As for the left out lane... genius... insanity... maybe a little of both, either way it's very innovative and original. I like the fact you have to earn the time to keep the gate open. Very clever. Would enjoy seeing some gameplay video of this in action if you're ever up for it.

This is a great title for it's era but one that is ripe for upgrades and improvements. A modders dream. Nice work!
