Now that is a surprising question!
Have you been living under a rock over the last year? Just kidding, but Kickstarter is talked about everywhere.
It is a crowdfunding system. You have a game project (or any other project) that needs funding to get going, you start a campaign on Kickstarter. You show people what it's all about, and say how much money you need for it to become a reality; and people pledge money for you. If you reach the amount of money you need within 30 days, you can produce yor game. If not, then you won't and the backers don't have to pay.
In order to motivate people to invest in your project you promise rewards; like everyone who spends 60 Euros gets a copy of the game when it's done. Everyone who spends 80 Euro gets the game and a poster. This can go upto several 1000 Euros, with more extravagant rewards like meeting the developer or something.
Anyway, it is a very successful platform and over the last year it has been in all media because great classic games are now getting sequels thanks to the original developers raising enough money via Kickstarter where no publisher was interested. And plenty of homebrews/indy games get funded too.
Now about the release of Another World/the possibility it won't be released if not enough pre-orders are made...
I understand RGC is a non-profit organization, but why did you choose them instead of asking a professional publisher? People like Super Fighter Team, RGCD or or own Watermelon might have been interested and maybe could have released it without pre-orders, with professional webite, probably getting more media attention and selling more copies of the game.
I mean, the deal is made now, but the situation seems a bit unlucky now with the need for many pre-orders and the limited media attention so far. Personally I think this could have worked better with another publisher since Another World is not an ordinary homebrew but a rather big title with a well-known name. Now people feel pressured to pre-order and have to fear eBay-speculation to go wild with whatsounds like a very limited release.
Anyway, I love the project and will see if I can pre-order in time. The price is fair, and the product looks great. You can be proud.
