A band and a videogame, have different market crowds on Kickstarter.
I just tell you that to not get discouraged by irrelevant conditions.
But that's not the point here.
I have a suggestion for you.
It's what I do.
I can not guarantee you that it will work but...
it's better than nothing right?
Make a game with what you got.
Maybe a prequel to your main idea,
maybe something completely different.
Just make sure it is worth the time to be played, and it can draw the player's attention somehow, in the first 5 minuter.
An action game draws attention with action, an RPG with things happening and being interesting as a game from start,
Some game s build an atmosphere the user loves at first sight...
You can then upload your game for free.
If people will like it, you got their attention.
Take for instance the success story of Yatzee.
5 days a stranger debut. /// EPIC free advanture.
7 days a sceptic. /// Almost impossible to beat without a guide (hiding scene) but still an epic game.
Trilby's notes. /// His third game changes gameplay interface (risky) but gives great information for his epic lore behind the trilogy.
Finally,
6 Days a sacrifice was the end of that game series, that glues everything together.
The guy is a professional reviwer at the moment, with a fanatic crowd.
Cause he got the gamers community attention all right!
Bottomline trust yourself, do your best and you will find your way.
Edit: Forgot his foul language so I remove a suggestion link.
