I saw something about dual booting. I know you want to game but start small. Try a virtual machine. They aren't difficult to setup and there are hundreds of easy tutorials. Get a feel for Linux. See how you feel and then dual boot. When you are comfy then migrate the truth is this community pushed Linux hard and that's because it is mainly FOSS and it is private or more private rather.

However, no matter what anyone wants to tell you. Linux absolutely has its quirks and sometimes they get technical. There is a learning curve and some issues can divulge into multiple problems. This kind of thing can be frustrating but shouldn't stop you from learning and experimenting. I like Linux but I also appreciate that Windows for an average consumer does what it needs to.

The other thing is there is one OSX and up. There is one Windows version. There is an insane amount of Linux distributions. The easiest to learn are Ubuntu, Linux Mint, and if you want something more lightweight and true to force you to learn then you can just install Debian.
