1) In what programming language will it be coded?
100% javascript except the deployment mechanism and other various miscellanea background development tasks.
1a) What libraries will be used?
Primary in coffeescript, processing.js, node.js, and some type of database that I have yet to picked out.
1b) Will I be able to run it on a Linux system?
As long you run a modern browser(Chrome and Firefox 4), you'll be fine. Not sure if I can support IE9.
2) Will it be open sourced or not? (Not a requirement for me to donate, but still good to know).
Even better. It will be public domain addition to being open source. No string attached. It will be tripled public domained for good measure. CC0, Unlicense, and WTFPL. Choose whatever make you free the most.
3) What are your plans after releasing the game? Support and more games?
I'll continue working on it either in maintenance mode or in steady development. It won't be the intense development cycle that was in alpha. It really depends on how commercially successful this game at that point.
Otherwise, I will be looking at freelance jobs or asking money for my next game.
4) When do you consider it to be finished (and have the funding being paid out)?
When I completed gameplay features and entered beta. Every week, users will get to test out a version. Pledgers can pay all or pay partially. This process continues until the game is completed.
P.S. I really need to complete the rails site I was building for automata-rts and put all the answered information and stuff into one slick marketing copy.
