When it comes to video game development, advances in technology have allowed nearly anyone access to the tools required to create a video game. Of course, the average person lacks the same channels as triple-A studios, but as long as you know the basics and are dedicated enough, you can prove yourself as an independent designer.

Open-source video games are one of the prime examples of giving the ordinary player the ability to develop a game. Because of the availability and community aspect that open-source software grants, open-source games can develop a deeply dedicated player base. These open-source built titles represent the finest around.
