10 Million isnt enough to make a console game. They HAVE to be getting a substantial amount of investment from outside sources. Anyone telling you that an extra 5 million will change the design of the final game in any way is kidding themselves. The only this the kickstarter is doing is proving to outside investors that there is an audience for this game.
Anything you have read to the contrary is a mistranslation, misinterpretation, or something similar.
Games are very, very expensive to make (on a console/AAA level)
Google average salary for artists, coders and designers, and then imagine the number required for this kind of game, how long they will be working on it, and do the math.
There is no way this game gets made for less than, say 50 million.
