So Nintendo fans aren't confident that their fanbase will support a mere $250k in 17 days? So even Nintendo fans don't place trust in their fanbase to buy games then right? That's exactly what you're saying. You've got three fanbases that put over a million in less than a day, but Nintendo fans who have had most of the games in this style on their systems still haven't funded the game.
Also you're talking out of your ass. Yes, most funding is done when the funding is first available, because most people interested will immediately put money down on it, but you're just spewing bullshit out of your mouth by stating that it's going a hell of a lot faster than it was two days ago(now three days.) Starting yesterday mirror sites for multiple different regions were added so the game can get support from different languages, but even then, it's only received $150k in three days. The kickstarter hit $2m on the 15th, it took until the 20th to get $2,500k, and the 26th to get to get to $2,750k. So it has dropped drastically after hitting the latest goal, taking six days, but the rate it's going right now, it'll still take five days to hit the following goal, and that's hardly "a lot faster."
Right now, no one can be certain any additional increase in sales now though are due to the Nintendo fans or because of support the game is getting from the mirror sites in other countries, but what we do know, based on how much money was gained since the announcement and right now, is that there's a large certainty that Nintendo fans didn't put jack shit into a game that they were bitching and moaning since the announcement on getting.
