I wouldn't have had as much of a problem with this if it showed up on, say, indiegogo (whose whole thing is letting you run crowdfunding for whatever you want.) I dislike it on Kickstarter because Kickstarter pretends to have standards, one of which is no lifestyle funding, and this is pure lifestyle funding for the kid. She's not promising to take what she's learning at RPG Camp and apply it to making a game specifically for the Kickstarter, she's promising to send everyone the game she makes as part of the camp's instructional sessions. Essentially, pay for the kid to go to camp and she'll go to camp. Fund My Trip To Disneyland, And I'll Send You A Piece Of My Ticket!
There's nothing morally wrong about trying to get people to pitch in for your kid's tuition, but it is an apparent perversion of the Kickstarter rules, and there are crowdfunding platforms out there that would have allowed it without seeming dodgy. Kickstarter being okay with it is equally disappointing, but not terribly surprising.
I also really, really don't like the branding present on the merchandise being promised as rewards. That particular thing does seem opportunistic, and raises the worrying possibility that mom's gonna try to cash in on this by launching Keep Up as a movement.
