I believe what happened was that the kick starter people actually complained, because Planetary Annihilation was originally on steam for much cheaper. Those that had funded it via Kickstarter (who receive many more benefits then simply buying it on steam) argued that it shouldn't be cheaper for the same access.
However if you look at it, its $90 for Early Alpha access, this price will run June Through August.
Then in September through November, the price will drop to $60
Then it will enter its retail price in December, which will likely be $40
The reason is what Krompt says. $90 was what you had to donate to the kickstarter to get early access. The game isn't finished.
Although, it's not true that buying it on Steam cuts you out of the $90 donation level goodies offered in the KS. If you pay $90, you still get the same stuff you would have gotten if you'd paid $90 back when the KS was open.
Um, so yeah everyone's been QQing about this all day long, where does it say you absolutely must buy the alpha or beta?
nowhere, but you're missing the point, if people support this, they're sending the signal that we accept outragoues prices, 60 euro for a game now, is bad enought, but how would you like, a year from now, that the asking price on steam, is 80-100 euro per game, that's is what's gonna happen when you blindly buy a game, in alpha, for such outrageous amounts
oh, and btw, this is by no means a triple A title, its a indie game, so lets raise it to 120 euro, for say a EA game, have fun with that
at best, this should be 15-20 euro for alpha acces, and even then, its pushing it!
