Just finished act 2 again tonight. What an experience. I ultimately had more fun living this story than Halo, to be honest. Incredible.
I really hope to see this whole project finished someday. Playing it all the way to the end, including voice acting, is top of my video-game-dream list. Heck, if the rights to Freespace are ever up for sale, this could very feasibly be packaged into a standalone and released as Freespace 3 (minus a few alterations to Age of Aquarius that would fill some MAJOR plot holes...)
I'd love to help voice act in any way I can.
