No, people are paying $32.00 for alpha access,
and beta access,
and the full game (when it releases).
They're using a "Minecraft-style" business model. If you support the developers by pre-ordering the game early, you pay a discounted price as a reward (in this case, $32) and you get all future versions of the game, including the final release version.
Once the game leaves alpha and hits beta, the price will get higher (maybe $40), but it will still be discounted for people getting in early. Then, when the game is finalized, the price will finally go up to $50 or $60 MSRP or whatever.
From the
store description:
The "Alpha invites", on the other hand, are free passes to the alpha that paid users can give out to their friends for free. It does not have the same benefits as actually paying for the game though; in this case, it doesn't include access to the full game. Just alpha.
