Hey !
First I must say The exchange student is one of the best games that was released recently ! but short (yeah yeah you know that...).
I already know most of the answers to my "identical questions" i've been posting to other developers, but still here they are copy pasted for sake of other curious people:
1. What game engine and technologies are you using to make the game ?
2. How are you funding the production of the game ?
3. How much did making episode 1 cost, and has been a commercial success so far ?
4. do you have any tips and advice for us independent game developers out there working on their first game ?
some TES specific questions:
5. Are you working from a central office or over the net ?
6. what stuff are you oursourcing and what are you keeping in house ?
7. can you describe a little bit your current work proccess for making the game ?
