Yes, it's very well known games in Early Access do not need money. EA-devs get no loan. Buildings cost no power. Royalties and subscriptions do not need to be paid. Airliners have special EA-developers fly free packages. As long as a game is in EA-status, it's developer has zero-cost.

Or in reality; They need the launch money. This will reduce the money they gain at EA-launch, meaning less time can be put into finalisation meaning they can work less on the game, and probably have to release it sooner than anticipated, probably premature and rushed.
But yeah, sure, see no issue with that.

@theflightless: So you support Kickstarters being made mouthdead. Apparently some people actually think that's a good thing and I wonder... what the hell people? How insane must you be to dismiss the opinions of one group of people due to where they bought the game. Why could you possibly think only Valve-buyers have the right of an opinion. I can see why Valve think that (It's a dictators wish) but WHY POSSIBLY would a gamer support that?
