The problem is you are console gaming. Early access like this is the norm on PC. SNOW is a good example. Skiiing game, ala skate, and i've had it on early access for over a year (I think Luft told me about it). There's a forum on steam for it, people give input and the game is updated and improved on a regular basis. "The Golf Club" was the same way, years before it ever released on console.
This is what's happening here. I'm backing it the same way i would buy and early access copy on Steam. I support it, give input, and receive (usually) a copy for free or a discounted rate at the end of early access.
