Thanks guys, you have definitely given me food for thought.

I like the idea of fold drives very much. Actually I liked the use of wormholes and the warp factor cubed.. so maybe it wouldn't be a bad idea to just have multiple means of travel in the game, a primary means of travel and then a secondary, followed by a naturally occurring phenomenon in space (wormhole)

Think that would keep my bases covered.

How would you propose the folding space rule would work?
For every higher degree of folding capability, increase the distance and difficulty *2 ?

What would you consider a good starting distance to be able to fold space at the first stage? Hmm.. maybe 1 parsec. That's quite a good distance..

So what say ye?
