What you are implying is that if people don’t have anything optimistic / good to say, then they shouldn’t post here. That is kinda ridiculous and not how things are or should be done. People helped fund / kickstart the project, follow the development process for years, so stating that things haven’t looked that great so far is nothing outlandish. The fact that the whole development process is based on interaction, funding and other stuff in cooperation with the community makes some degree of scepticism all the more reasonable and there is nothing hysterical about it.
Yes, noone really knows how good the game is / will be, but writing an opinion on how the development process goes after it’s over is no good, is it?
