Years ago I was active with Game Institute as a student and I participated in several of their Game Programming Challenges. In fact, that is why I created the demo that I’m using for the A Summoner’s Tale series from. I was surprised to get an email from them that one of their games made into onto the Greenlight program on Steam. The game rapidly rose up the ranks and is poised to hit the top 10.
Due to the remarkable success they are offering 50% off of their membership fees. This includes access to libraries of free source code and assets that you can use in games. I’d suggest that if you’re interested in different aspects of game programming to check them out.
