Would you pay $90 for a "Triple-A" game with rave reviews from critics and gamers alike?
Would you pay $90 for an average game that's a sequel to one you've already played?
Would you pay $90 for a game that's released and whose premise you like, but you've seen and heard nothing about it?
Would you pay $90 for an alpha release of a game that may fail in its release state?
At least with a preorder, you can cancel it. But to pay $90 for a game for which you have no assurance that it will ever live up to expectations is insane. I wouldn't personally pay that much for any game short of Baldur's Gate III itself, even if it was a released, Bethesda game with rave reviews. For an unfinished alpha release by an indie developer, they're actually taking the piss. Early adopters, alpha and beta testers who fund a game in its development stage should pay a fraction of its release price, not a multiple. The developers are really trying their luck (and follower's goodwill) with this farce.
