Lets face it, unless you're kinda like Navi from a certain abridged series in the sense that you think TF2 is the only game in existence, (compared to her thinking that muffins are the only food in existence), you most likely have other gaming options, be it on Consoles or on your PC or, dare i say it, an Ipad or other mobile device.
that said, I've been playing Torchlight, Sonic Generations, Kid Icarus Uprising, and to some extent Magicka and Binding of Isaac.
(also TF2 is a given here: after all, the servers are for TF2)
