Hey Johnny, I couldn't find it on Steam so I found the website but they still show a special Early Bird preorder price of $20 bux calling it Steam Early Access Nomad. There's also a $40 Closed Alpha Nomad and a $100 Collector Nomad on the site.
I wonder if the $20 Early Access is still actually available.

I think all packages should be available... Seeing how it's just digital goods... some have physical gifts, but I don't think many will spend $100 on an indie game...
