As a communication "90$ for early access" is probably misjudged. In isolation it looks grasping, whatever the forum. If a game I was interested in launched a Kickstarter and $90 was the bottom tier I suspect I'd have a similar reaction.

In the context of $40 for the game, $60 if you want beta access $90 if you want alpha access it feels a lot more like they are giving bonuses to people willing to support them over the odds. It will look a lot better on Kickstarter than on Steam but it's a coherent message wherever.
