My main issue with Wayforward was how they just seemed to use KS to not really put their own funds at risk, and the level of service IMO went hand in hand with that broken mentality. I got what I paid for, and I didn't have the issues that others appear to have had, but the lack of care or any level of priority seemed lost on these guys for no other reason than they could(very low risk to them personally).
So while I didn't swear them off after KS, I did decide I wouldn't support their new games until they are at a great discount(50% at least). I'm happy to support this book, as this is mostly UDON who I have been happy with for years, and while WF will get some proceeds, I'm happy to support UDON as well(I want them to do well). If me not buying WF new at retail means they no longer make new games down the road, I'm cool with that, as after that KS, and how they took funds they really didn't need, to only deliver service like they had better things to do, spoke volumes to me.
As for KS in general, I've only had 1 really bad experience, and that was from a company who I had dealt with before through KS, so I had no reason to believe things would go tits up! And while I didn't get specifically what I paid for, I was able to get an outcome that was mutually acceptable to both sides, so all was not lost even in that bad situation(or so it seemed). LOL
