Gabelvampir: Yeah I really hope it "just" a cash grab, and not money they really need to complete the game and make it bug free.
Although that Kickstarter broke records, many overlook that Kickstarter pockets around 40% of the funds collected for themselves, and the game had a false start with IntiCreates, then switched developer (no idea if it was started from scratch) and then also needed WayForward to polish up the graphics. So it could be they really need the money. Or their publisher 505 Games wants some more return of investment, but I have no experience with 505 so I can't say anything about that.
As I said, let's hope it is a cash grab / financing the next project, and not money needed for completing what was promised.
Even if it was just a cash grab that still wouldn't be a good thing at all. Also it would be incredibly poorly timed considering all the present issues. The argument is not that they are taking away people from development for the cosmetic dlc, but the fact that they are more concerned with generating revenue than doing a proper update that fields the concerns of backers.
The cosmetic dlc poll was all 505 Games. If it was a proper update by IGA/ArtPlay there would of been more to it than just a hit and run post with a poll link. Sadly the devs are probably working on the switch version at the moment and not any fixes or the promised stretch goals (you know, the free dlc that they are giving away to everybody that buys the game from their own big hearts, even though all that content was paid for by the backers some time ago).
This also isn't 505 Games first rodeo when it comes to crowdfunded projects. They had a hand in Underworld Ascendant, which seemed to have gotten very mixed reviews and had issues right out of the gate. More research would have to be done concerning that campaign, but their track record doesn't seem to be the best when it comes to this stuff.
Also, do not forget that the game is selling pretty well due to word of mouth. If they are having revenue issues it would be because of all the extra work being done to fix the switch version (which remains to be seen). They have promised patches that would fix a number of issues for all available versions but that also is currently up in the air. Sadly it is a wait and see for the most part.
