Well no, some of us only get the BETA, but hopefully the rest of us backers get to see what's going on in the Alpha.
We got a preview of last livestream, not to mention we named both the Mod Market and the Replay System. The Devs have actually been rather good at giving backers something to chew these past weeks.
OP: Maybe you should upgrade your pledge to the level that constantly reminds you that you're a backer with a series of personalized messages from the dev team reminding you of their indebtedness to you. Oh wait... that doesn't exist!
I'd imagine he'd be able to get that sort of thing with several million dollar's worth of no-strings-attached donations.
