content: Basically, use a Windows machine if games you would be playing or are interested do not run in Linux well or at all (which is why I'm doing it.) You can check this easily - if a game is not native to Linux, simply search the game's title along with "winehq" and click on the webpage. For example, Skyrim's page Here you can see which games will work and which ones will not. I am running a VM because of the lack of support for Phantasy Star Online 2 as well as the poor performance in Guild Wars 2.  If you do not have any games that you want to be playing that do not work in Linux, there's very little reason to actually run a VM.
