It was a good idea at first the kickstarter thing now it has become a place for even developers with cash to draw in even more cash, some of the games on there will happen wether you throw your cash at them or not.
I don't disagree, but I think each Kickstarter campaign needs to be weighed on its own individual merits.
I have backed various different campaigns, after making sure I researched ( as much as I could, in like, 10-15 minutes) so I knew what I was getting into (as much as possible).
Some games would not be developed at all if initial seed money did not get it going. Some games might get developed w/o, but then the designers & dev's would have to follow the orders of a big, bad, evil, money-grubbing mega-Corp, which would rip the soul out of a game. And some had seed money, but wanted to attract more to show the initial investors the idea was worth developing more (i.e., original backer wanted just an iOS game, but designers wanted to make it for the computer/grandpa box).
That being said, I've hit my limit...I'm backing 5 games, and those will likely keep me occupied until 2019...but I'm always curious to see what the next great idea might be.
You also have to ask yourself, can I stomach uncertainty, and paying $$$ now for a game that may not be out for another 2 years.
