Fortunately (unfortunately?) I don't really play that many games. The few that I do play won't run on modern Windows operating systems anyway and I already have an XP virtual machine to play them (Civilization II and Diablo II). The other random games that I play are browser-based.
I'm just tired of fighting Windows when trying to do development work. I hear what sneaky is saying - putting too much together can cause issues - but I rather not have multiple physical machines when one will do (with VMs), plus most of what I "do" on the computer (aside from development work) is web browsing and watching movies - things Linux can handle easily. The simple fact is in the web development world, Windows is a distant second-class citizen. The only way I'm going to able to breathe Linux is to just dive in. I am also noticing more and more job postings that require Linux experience. Might as well learn it from the inside out.
It's also nice not being in school or having a job that requires Office, though a VM can do that, too (but LibreOffice is pretty well equipped).
