It's not as insane as it sounds though, as a new game allows me to test and develop new scripts that I can use in Legacy, without having to worry about accidentally breaking Legacy while making new scripts. For example, in 17 Peach Street, I've just spent the afternoon making a flashlight script that's affected by walls. And it's not just on or off either, the lighting goes from 0% to 100% with 20% intervals. Now that it's working, I can use it in Legacy! And I didn't have to muck about with the existing code or maps in Legacy, allowing me to make a cleanly portable script that I'm sure works.
Here it is in action:

Anywho, it's 2 in the morning, and I should be getting to bed. Cheers!
