Unless you're a recognized name in gaming or the geekosphere in general, then you really need something playable to demonstrate your general competence if you're looking to Kickstart a gaming project - concept art, promises or carefully spun demo videos don't really cut it.
just saw this thread,
*takes notes* I never jump into something like this without thinking it out fully first.
I'm sure a demo video of actual game play and cutscenes ETC. would do the trick. heck I got some support for one of my projects by inviting some people to watch me make basic game functions in live stream.
but that project is canned till Zonesama develops the character more, he said he's not ready for a game about the character yet.
oh well, got my own stuff to do, thats always the best route, but yeah even I get desperate for cash sometimes and think of kickstarter or indegogo. but I never follow through cause I don't have enough to show lol. I've got the game-play but it's all placeholder meshes, lol yeah people are gonna pay big bucks in support of the adventures of Mr. Basic Cube. *sarcastic*
