This is how a good game franchise should begin: A team gets together, makes something they think is really cool, and release it for free. They get feedback and love and make a sequel with more content. Then they make it into a full Steam game, after having tested all the core elements of gameplay very thouroughly.
Pro tip: Send one high-skill person to do a job so it gets done quickly and safely, AND send several lower-skill people along with him so that they all get skill boosts. I managed to train my entire population to be skilled soldiers by having them go with the veterans for killing missions (and it works for building, too).
