pottedPlant7p The point of Kickstarter for games is to get the game development funded without a publisher fronting the money, setting deadlines, conditions, etc., that normally happens. A publisher wants more control because they’re fronting millions of dollars that they may or may not get back. Crowdsourcing works around that, paying for development without the same strings attached.
Selling the game is something else; EA is making a special offer to make sure they offer it in their online store. Steam is a store. Impulse is a store. You get the idea. The benefit to game makers is they don’t have to deal with the business aspect (processing payments, hosting, etc). That frees them up to do more development and/or get on with their lives. Certainly, the hope is that people other than those who funded the kickstarter will buy the game! And some of the kickstarter folks pitch in major money – hundreds, even thousands of dollars. I don’t think any of the major games I’ve seen say, “Hey, we’ll release the game for free if successfully funded!”
Also: EA doesn’t have the marketshare to ask for exclusitivity. Valve does.
