Overfunding is the greatest enemy of an enthusiast project. It is hard to not go "Now I can do everything I dreamed of!" when you look at 24 times the money you budgeted for. But in reality, you cannot. A ton of money is not infinite money. You still need to budget carefully, even if you have more zeroes to write.
This always intrigued me. Can you just say 'well, we got 5 times the money we needed for this crowdfunded thing we're doing, we just give em all the tiers we promised on our Kickstarter page and keep the rest of the money'. Or are crowdfunded projects forced to do more when they got multiple times the money they actually needed to fund the thing they're doing?
