How is the compatibility to the gaming world with Beta 2 10.1, and how does it compare to other systems like Windons? Also, I'm trying to learn every OS system out there because I'm learning computer science in school.

Welcome aboard.

The BSDs aren't gaming O/Ses, having said that, they can have Linux compatibility, so can run games that work on Linux.

Probably best you stick with 'unix like' systems, (though Haiku & MenuetOS might also interest you).

For games available for free like Xonotic it will behave FreeBSD/GhostBSD better than linux and Windows if you have a well supported graphic card and mother board. The ports contain a bunch of free games. Minecraft is in the ports.

For the latest games on Windows stay with Windows.
