I had idea about creating jazz related freeware RTS...
but I had no engine where I can do it without programming... But finally I found Scirra Constructor... And little tutorial...

I can begin the large project from it and I can make freeware RTS for fans... But I have two questions for you:

1.RTS actions must be on planet or in the space?
2.It's must be spaceships, or rabbits and turtles with guns?
3.What's your favorite planet from Jackrabbit's world (Example: Carrotus, Diamondus, Technoir, Medivo and etc.)
4.What's gameplay should be? (Destroy enemy flying/nonflying base? Capture the planet? Capture all points..?)

I have 3 free months to do this work... Well, if you have any comments or ideas how to make this RTS more better, post here...
