I love the possibilities that this mod adds to the play-trough. I have used creative scenario maps to test builds but it gets crumble-some after some time to close the current map and load the creative one.
One thing I would add is a research limit so that you don't have it enabled from the start and you get a progression kind of like vanilla play-trough. Another thing is to only let you use things that you researched already, like beacons and the like, but it kind of defeat the purpose in the late game.
