I don't know what the net worth of Brian Fargo is, but I would imagine a not-insignificant part of it is invested in InXile. He's also pledged 100k toward their current Kickstarter, Tides of Numemera. And I'd imagine the ratio the cost of a game to to his net worth is wildly different than the ratio of paying for your own child to attend RPG camp to Susan Wilson's net worth
I imagine a fair amount is wrapped up in inXile, but he is a millionaire several times over: he's the founder of Interplay, which went IPO in 1998 when he owned 45% of the company and he left in 2002, long before Interplay started tanking.
To be clear: I think it was a smart move for him—regardless of his net worth—to use Kickstarter, and I think it's an even smarter move—PR-wise at least—to put some of his own money into the Kickstarter (albeit in the end a bit pointless: he could've just cut that amount off the top of the asking amount). I just think it's silly to think people who can self-fund can't use it.
