Why shouldn't publisher kickstart all new IP's and remakes of old titles, if this method is acceptable? If it's just about 'gauging interest", then the only thing a publisher should green light with their own cash is sequels of recent games that are less of a risk (Gears 4, COD X, Forza 6, etc.).
Spend their money on sure hits and then kickstart all new IPs and anything that is remotely risky.
Ubi should have kickstarted Watch Dogs. Why should they take 100% of the risk. Let gamers put "their money where their mouth is". If they want new IP, then fund it before hand.
I think the "put money where mouth" argument is flawed for multiple reasons. Mainly because people will put the money down if the game is 'good' and presents value relative to the competition it faces in the market upon it's release, and if the consumer still has money ( job loss, have a baby, etc. ).
The reason I don't kickstart projects is because I prefer not to put my money down until I know what I am getting for it. That is why I don't do season passes.
