This is, of course, the core value proposition of the Developr Access tier. That and the fact that you will be getting a copy of the game as soon as we can get it to you upon successful completion of the KS (much sooner than "a few months" before everybody else). As you will see during the campaign we have a prototype that is playable right now. It's still a far cry from the finished game however the dev team has already spent quite a few enjoyable hours playing it.
All early access tier forums will be a private section of this forum.
