I'm sure they'll reach the minimum. Will they reach the $250k stretch goal? Hard to say. They've stated that if they don't reach the stretch goal, they'll try to shop the game to publishers, which is a bit concerning. Will the publishers agree to providing the full game to the Kickstarter funders? Or will they only agree to providing some nerfed version with lots of cut content? Or will they require that the extra content be sold separately as DLC?
On a side note, I believe these guys used to be Spellbound. While Arcania was pretty bad, I enjoyed the Desperados games quite a bit. I'd love to see a Kickstarter for a new Desperados or Commandos game.
