I'd like Obsidian to somehow work towards self publishing, possibly downsizing along the way. Owning their own IPs and building up the number of games they actually get continuous revenue on, sounds like a business model with a future unlike their current one.
Edit : MCA appears to be a bro, so I doubt we'll ever see his Kickstarter while he thinks Obsidian could go under.
Again, there's not just 1 talented guy at Obsidian. Downsizing could very well result in others leaving. As mentioned it already got Ziets. Would you still be interested in Obsidian if only MCA is left?
Also I doubt MCA thinks nor wants Obsidian to go under nor get much smaller. You don't refuse payment for a year, so that others can stay on if you think otherwise.
IMO, they should do both. Utilise the Kickstarter model to get a game out, then use the profits to self-publish their smaller titles. The money and their own IP's will also be useful leverage in publisher discussions for their next bigger titles.
Anyway, regarding Kickstarter. Avellone has been awfully quiet for a while now on the subject aside from "we're working on it". Which leads me to believe that they are coocking up something big.
