Right now? I'm playing nothing.

In the last couple years? I've had an on-and-off relationship with Diablo 3. Ultimately, the amount of power/stat inflation drove me away from the game, and I probably won't ever grind it as much as I once did. In my mind, there's little point to doing anything aside from starting afresh each season and going all-out for a couple weeks, as all the gear one acquires gets antiquated by the next season (within 3-6 months). I (sometimes) try out the new content after a major patch but I don't stay around, these days.
