I actually have nothing I'm playing right now...which is never a good thing for my wallet. I end up buying all sorts of random stuff I'm only slightly interested in, in the hopes that something clicks.
I'd really love a new MMO, but there isn't a good one out there that I haven't already put 100+ hours into. I'm slightly intrigued by the the Sword Art Online series, but the reviews all say that most of the enjoyment only comes if you already know the characters and story from the anime.
Maybe I'll give one of the far-too-many 4X games I have sitting in my library a shot. Civ V, Age of Wonders 3, Warlock 2, Endless Legend, Fallen Enchantress...I've only taken a cursory look at all of them. Put the most time into Civ V, but don't think I've ever actually finished a game.
I'm sure I'll spend some time putzing around in Lineage 2 Revolution, but that's casual gaming at it's finest (I can literally start it and walk away for 5 minutes while it does it's thing).
If anyone has recommendations, I'm all ears.
