My apologies if I derail this a little bit...
The wife and I just flushed $17,000 down the toilet after a relative's business partnership, into which that money was invested over the last three years, appears to be headed for the swirly drain. Well, shiznits. What's done is done and I'm not going to change my relationship with my family member - we're adults and sometimes investments don't work out.
Here's the lesson, and I think it applies to cases like these alpha- or 'early'-release games: you're investing in programmers, not business people. "Me and Jimmy have this great idea and we're gonna quit our jobs to work on it full-time." Gonna go out on a limb and say that most of these little indie "studios" are winging-it when it comes to finances, budgeting, etc. That's a big part of what happened with our investment - we forgot that technical expertise in the business does not equate to business management expertise. We looked at their professional background and figured, "Yeah, they should have no problem with this." And we were correct as far as doing the actual work goes. But when it came to managing the financial and legal bits, an important part of keeping a business going, they didn't have the background. That, and the majority partner deviated from their growth plan almost right from the start, taking on too much too soon. That's also a management matter.
And that's how you lose $17,000 plus interest on something that should have at least broken-even. Live and learn. Next time - if there IS a next time - I'm gonna have my finger directly in the pie whether they want it there or not. If I'm going to lose another $17k then I at least want the satisfaction of knowing that I helped make it happen. ; )
So when looking at the estimated $1-2 million in income from this game, keep in mind that unless these guys knew to handle the money then it was a crapshoot all along, no matter how great the concept, how good the early screenshots and videos looked, how playable the alpha and beta are. This really isn't much different than a destitute lottery winner: sudden infusion of money and no idea how to use it wisely, and so it gets squandered.
As others have stated in various Kickstarter threads, you may as well accept that your early access money is gone the moment you click that "Process Order" button. There is no guarantee that the programmers will accomplish their goals programming-wise, and there is a good probability that they have no clue of what to do with the money they raise along the way. "We raised $23,000 but my car's transmission broke and needed replacement, so...." So what? I didn't fund your car repairs. Doesn't matter. Once they have the money they can fuck things up in any number of ways.
I hope cases like this get people to realize that programming skills and a good idea only get you so far. There needs to be a bit of business sense and budgetary discipline to back it all up, and I suspect most of these indie folks don't figure that out until they're in the thick of the project. In light of that, I think it's reasonable for a prospective backer to ask about the business, accounting, and project management experience of the principals behind a KS campaign or early-access project: they're asking you for money, so they should have no problem answering those questions.
