i agree that right now we are in the honeymoon phase.
grandiose promises, catering to niches
the first game that gets released that does not make the most vocal of their fanbase happy, will face a huge backlash.
"i funded YOUR game because i wanted features X and Y and you promised those features and you didnt deliver!!!"
notice i said most vocal....
or else the first one subject to numerous delays because they want to get it just right.
in other words, the first one that gets massive bad publicity for any reason... that will cause a problem. especially when you consider the life cycle of these. you will see people starting to want to invest later and later in the project.
so we will end up right where we are now where it takes a publisher.
it really could be done well, and create a boon for the market. but there will be sour grapes along the path. the question will end up being, were those grapes so sour they spoiled the harvest or just the vine.
