The process right now is:
• Create a new steam account for your server
• Buy a second copy of the game on that account (the 1st copy is the one you want to play on)
The future:
• Create a new steam account for every single map expansion they release for ASA
• For each of these accounts, buy a copy of ASA
So based on their current design, ultimately we are looking at 12 additional steam accounts and 13 total purchases of the game (your main steam account + 12 servers)
The Island, Scorched Earth, Aberration, Extinction, Genesis Part 1, Genesis Part 2, The Center, Ragnarok, Valguero, Crystal Isles, Lost Island, Fjordur
OR
Pay Nitrado an OUTRAGEOUS amount of money per server because they have a global monopoly on commercial server hosting.
This is just... wierd?
