Hi all,
Okay, a few wrap up points to questions I saw:
1) The version available from TotalGaming.net does not contain StarForce.
2) If you purchased the retail version you cannot register through Stardock Central. You'll need to re-purchase the game from TotalGaming.net.
3) The demo version will run for 2-years of in-game time. It is not limited by actual "real-life" time, so you can replay it if you want. I've played it several times and got 1-3 hours out of it. Note that zipping around space takes a lot of in-game time.
4) We currently have the latest version available to us from the U.S. publisher. If a new version is released to them, we'll update the version on Stardock Central as well. 
5) The downloadable versions of Space Rangers 2 (anywhere online) do not contain Space Rangers 1 (which is why the online version is $10 less than retail). That game is will be offered as a separate purchase at some point in the future, though there may be discounts for those who've already bought Space Rangers 2 from TotalGaming.net (too soon to say for sure). If that ends up being the case, we'll likely let buyers know via email about the offer.
Hope this helps.
