The game is on a 66% discount on Steam atm, but id rather buy it on GoG.
How come, there isnt any discount on this platform?

Because GOG and Steam are different store and they may haven´t the same discount =/

Because GoG-users are secondary citisens, and should be glad they can play the game at all!

What's next, you'd want to pre-order by investing in the developement all the upcoming games of this game/studio/franchise, like Steam-players can?

What an idea some people have.
