Shit Brian, who cares if it's a fucking exclusive. You shouldn't be getting into bed with EA in the first fucking place when you're using Kickstarter money to fund you.
There's two very good reasons not to go Origin. The first is that Kickstarter changes the fundamental developer/publisher relationship and elevates the developer above the level of common serf.
Publishers screw over developers like you wouldn't believe and any independently funded project has an edge over the traditional arrangement which sees publishers use milestone cheques to hold the developer to ransom.
Do you seriously think Wasteland 2 is going to get a reputation for a positive gaming experience on EA's piece of shit distribution service? A service which is known for its many issues and which will give EA the opportunity to create unhappy customers by screwing you over.
EA does not want Kickstarter projects to succeed. It undermines their fundamental financial power when negotiating with a developer.
Second is that EA are basically the same piece of shit cock-suckers who've been screwing gamers over to an increasing degree. Supporting EA is like giving a ride to the abusive husband who beats his wife because he'll toss you some gas money. It's selling your principles out for a couple of bucks.
When you finance shit yourselves, I don't care what you do - when you're using Kickstarter dollars, you really need to demonstrate some ethical cojones. Because WHO these donations benefit is a question that everyone will be asking eventually.
Does anyone seriously think people give to Kickstarter projects so the leeches at Electronic Arts can make a buck out of it? At least have the decency to state that shit up front before you start putting your hand out and asking for cash.
