The requirements should actaully be lower than SC.
If I get one copy of the beta will I be able to run it on the remaining 2 machines (since it is LAN only for the time being ) or do I have to preorder the game 3 times?
No license details have been announced for Demigod as yet, but in the case of Sins, we permitted the use of one copy for two seats in LAN play. So I can't confirm that this will continue to be the case here, but it's a safe bet. Yarlen should be able to confirm one way or the other.
