I thought it reaching 3 or 4 million was a bit of a pipe dream at the beginning, so hitting the "max" is pretty amazing.
It is also ending every strongly (about 40 mins left atm). It will come close to raising $2 million in the last two days alone. Also should be noted that it will surpass the previous crowd funding record for a video game by that same amount. Not bad for a "dead" genre.
