I will go through spurts of putting all my free time into a certain game, especially with new releases, then I'll bounce around with my normal games until I get bit by the next bug.
Right now the bug is playing TES V with the Beyond Skyrim: Bruma mod (It's the second most fantastic mod for skyrim, check that shit out! (The first is Inigo)).
After I get my fill, I'll be back to ARMA III, Insurgency/Day of Infamy, Space Engineers, Garry's Mod, etc and so fourth.
What I hate is when I get bit by the bug for a game that's not out yet, and play no other games because I only want to play X unreleased game even if it's still years away. OverHypeSyndrome.
