It is an early access game. Potential buyers should be aware of the game’s current status because they never know whether that “vision” will be reached or whether what you buy today is what you get 10 years from now.
If a developer is not able to take criticism of an early access title, they should not release their title in early access before it is done.
As always, don’t blindly take any opinion you see on the internet as gospel, try it yourself. However… every time there is a game with serious problems you get a vocal minority talking about how the “vocal minority” (who just so happens to be everyone except them) is trying to ruin the developer’s vision. I hope this is not one of those instances though because I do like FTL and i do like pirate/sail games (which is why i bought this game).
