15% of 400.000 is 60.000, though, and PayPal is very likely taking a fair share of it as well (about 3% I think)
Yeah, kinda sucks. Giving the money directly to the developers would be preferrable, but then we wouldn't have this sort of guarantuee of only being charged, when the project meets its funding goal.
There's still some risk involved regarding the developer meeting the 400.000€ goal and taking your money, but then never finishing the damn game (because of bankruptcy, delays, economic crisis, whatever).
