Thanks Kryo

Too bad I made the purchase Friday night and now have all weekend of no gameplaying

Will probably have to wait until next weekend before I can give it a proper go.
I don't think that many companies have their direct download pricing system setup correctly. With a direct download, their are no printing or distribution costs for the company, but the customer has to do extra work, e.g. printing manuals, creating backups, sorting out technical issues.
Basically, it seems like the publishers have to do less work regarding logistics, but the customers have to do more. Therefore, shouldn't there be a greater price differential?
RE: problem using different email accounts - The system really should allow for multiple addresses. I'm trying to play a game where I manage civilizations spread out amongst multiple star sytems. What are the chances that I am the type of person that has more than 1 email address?
Despite having studyied computer science at university, I found the online payment system confusing. I was bounced around :
https://store.stardock.com/
https://www.galciv2.com/Purchase.aspx
http://totalgaming.stardock.com/
and paypal
...this was before I got anywhere near Stardock Central
I hope Impulse is closer to what Steam was 5 years ago!
