I'm a big fan of certain online games and they are the ONLY reason I still use Windows. I think the drive to support gaming on Linux, regardless of flavor, will be a very good thing. As more support is provided for mass market users, the shift will become more apparent and pick up pace.
On the DM side, I've found gnome to be my personal favorite, but cinnamon, kde, lxde are all very nice too. Unity is far too awkward for my work style and lack of native customization is a deal-breaker. I typically work in a multi monitor configuration and the unwieldy management for that type of setup just gets my goat.
