I think there is also a big gap between the Indie people who want to make a game and which are looking for support on kickstarter - and indie projects which basically want to collect a huge budget to make an AAA title. While the first group looks for like 10.000 to 100.000, the second one can be found between 150k and millions of $ - the price might be realistic to make this kind of game, but in this case kickstarter is likely not the right platform.
Some examples from the games I backed:
Legends of Eisenwald, Goal: 50k
Xenonauts, Goal: 50k
Malevolence, Goal: 6k
MORE, Goal: 50k
Limit Theory, Goal: 50k
Barkley 2, Goal 35k
…
and so on. On the other hand you have the big budget projects from people who might or might not be known from other games:
Dead State: 150k, made it
Shaker: 1million, failed
Sui Generis: 150k Pounds, just made it
Maia: 100k Pounds, only made it with Total Biscuits help
Thorvalla: 1million, failed
And there is also Banner Saga, which I would say is almost a prototype of the successful AAA kickstarter moneywise, because even if they had some "guys from bioware", they kept their goal pretty low.
I think there is a lot of new ideas and innovation in the small projects and I think these can work out well. But as soon as the project goal is over 100k they better have a big name to build on or some awesome gameplay footage to show.
Kimuras project is in this second Range, and with what he saying he is purely pointing to all the big projects. What he is ignoring though is the tons of smaller projects which flourish on kickstarter besides all the sequels he is talking about.
