I wish it was like this, most of the time to me it seems like the other way around, they promise everything and don't know how to budget or how much taxes they have to pay so they end up with not enough money and just fail outright or seriously under-deliver.
I have some complex feelings about Kickstarter. I tend to back pen and paper RPGs and some like Feng Shui 2 and Nightwitches are fantastic and have brought me absolute joy while others like Second Skins from Monsterhearts https://www.kickstarter.com/projects/1571708637/monsterhearts-second-skins and Urban Shadows (a WoD hack of the Move System), have been a disappointment. Though both of these projects were completed, they failed to either meet their stretch goals or incorporate player feedback during the game's development phase. The Second Skins particularly are an interesting misfire because the creator was able to make an initial product which I enjoyed greatly, but most of the extra money went to the designers extremely high (and unexpected) medical bills and none of it to the stretch goals (he was going to hire a bunch of folks to do extra work with that money). I suppose the attitude you can take is that a Kickstarter is more of a patronage than an investment. You are supporting an artist so they can create their art and rather than Patreon which gives a money in increments. Therefore, you are tossing a bunch of money their way so they can work on one specific project.
The issue of planning is by no means unique or to Kickstarter; mismanagement of projects and design expectations is as old as ambition itself. The only thing Kickstarter does differently here is highlight just how unrealistic audiences expectations can get. They only deal with the finished product, not the long, difficult process of creating something as complex as an ambitious video game.
I've started kickstarting when Larian did Original Sin. It was a really impressive story; they really delivered on almost every goal, and the fans weren't in riot over the missing feature (such as day and night cycle).
I find the prevalent attitude of "kinda like online shopping" towards KS really confusing. Development is risky, so the end result is never guaranteed. If you can't accept that, then don't back - buy the finished product instead... IF it ever gets done, that is.
