Indie Simulation games
Indie Simulation games will provide you with simulated reality (or fictional reality) and will put you in charge of maintaining that reality. As any simulation, Indie Sims will take various aspects of reality and put them in the game to make you operate under given circumstances. There are many types of simulation games and indie developers create even more interesting and unusual ones since they can free their creativity the way they want to.
Indie Simulation games are smaller and more unique or can take some interesting turns as they are made by independent developers.
