Why don't you see if you can try to make some sort off a deal with Steam, so they distribute Universe Sandbox on a Disk? as some potential customers may not feel comfortable handing over there Credit or Debit card details (as this is needed for an online purchase) to distribution companies, plus it may even help to get universe sandbox into popular gaming shops such as "Game" and popular shopping websites like "Amazon" (I use
www.amazon.co.uk) this would result in an increase in profit and a increased fan base
The main reason for this suggestion is because my school runs an Astronomy Club and I think it would be better to have a Disk Version to put on our school server, if we ever want to use it during a club meeting, also i don't have a Credit or Debit card for steam.
Thanks
