Be careful of what you wish for... You just might get it.
I only invested (donated, or whatever) on 2 kickstarter games. Planetary Annihilation, and Star Citizen. Why? because i did trust the developers to produce a decent product. The former i am disappointed with, but not to the point of "nerd rage". It's just an average "ok" game. The "awesomeness" factor they pushed went out after the first asteroid strike. Now its just Total Annihilation on spherical maps with a Starcraft paced frenzied click fest added to it that gives you absolutely NO time to think. Not my cup of tea. No biggie. I pledged the minimum, and i don't consider it a loss.
Star Citizen on the other hand does have the "awesomeness" factor from what little i played of it on my system that it just barely works on, because it doesn't have the specs. Still the love that is going into that game SHOWS, and when i can build a system that can run it smoothly i am going to be spending a lot of time on that game. So i consider that a very Good Investment.
There are many kickstarters that seem "shady". I do think some of the pledge prices are ridiculous. Why would you want to pay $100 for something that may never happen? (and has "never happened" lately with quite a few games). That they don't even have any alpha footage, or one line of code written for it yet? Just so you could get the rhetorical "T-Shirt"? or whatever their so called "super package" offers? HELL NO!! Show me a damn product FIRST! Show me proof that you will follow though with your "claims", and not cave in, and shut down after you get 10 grand, or else I will keep my money thank you very much.
The phrase holds true for this as in anything else... Buyer Beware. Do your research before you invest.
