No world hop, I assume if you want your blast furnance to run at a private world you wouldn't want bot more then 6 hours anyway?
I would pay but people will still be stingey and hop over to every world to find the one that is running.
Khaleesi,
IF you were to run the 3 workers, How much would you need to keep it running - total costs?
adding a donations section could help, im sure bonds aren't shit to people after they find that there is a successful world plus all the money that they've made from you they should be thankful, i'll even pay your starting bonds to get things running and i only have 22m all thanks to you.
