Actually, while Kickstarter has a broader audience, it would be particularly difficult to be funded by them. A friend of mine and I were heading up a massive project once. It was a sitcom, and it was going very well. We had everything we needed apart from a seemingly small amount of money (less than 10,000 to shoot over 90 minutes of comedy, including the cost of equipment!). However, Kickstarter wouldn't allow us to post our campaign. Their restrictions are very difficult to comprehend and work around. This is why I personally prefer Indiegogo. You're likely to find more success there. The audience may be slightly smaller, but you're also more likely to find people that are interested in what you want to do. Not only that, but your project is more likely to be shared (assuming you promote it well) by your backers, expanding your audience. I strongly suggest that you focus solely on using just one campaign, so that you can put all of your efforts into advertising that one campaign.
You can check out this campaign for a great example of a well-done, game-related Indiegogo.com campaign. http://igg.me/at/the-game-crafter/x/2749882 This is a company that creates board game prototypes on-demand. They had a select audience, yet they very quickly received all the funding they needed - and they're still going! There are also examples of this on Kickstarter, of course, but Indiegogo really is a better, easier, and simpler option.
