I fully support this idea. I strongly believe this game is going to be huge. I'm a teacher in a school in the UK. I currently run Minecraft servers for the pupils so they can interact in a safe way. The scope having servers for the pupils is huge. They really respond well to implementing games into their education plans. As an educator I feel strongly that we are missing out on a big thing with games and education. Most games just don't consider the benefit they can have.
I have zero issue with paying more to help this game develop. My only wish is that it is released to steam EA only when it as lots of features and less buggy. Please do not rush this into EA. The potential is very real.
Also I know for sure that schools in the UK will pay for more than the $500 asking price for 100 keys :) Just a heads up.
