Things I've been playing recently:
TERA - Been dipping back in after having not touched for a while. Not sure if I'm going to stick with it, but I like the feel of the combat.
PlanetSide 2 - Another one from my back catalogue that's made an appearance recently.
Destiny 2 - Thought I'd give this a try. First foray into the franchise - enjoying it, although haven't a clue what's going on.
PULSAR: Lost Colony - Had a few games of this, and had some fun.
DCS World - Pushing over to simulator rather than game, and not the friendliest of titles to beginners, but if others have copies I'm sure we could engineer something interesting.
Arma 3 - Similar to the above, to an extent, although I've got rather more experience with it (still not particularly skilled, though...).
World of Warships - OK, not actually played this one recently. Thought about playing it though. Sometimes gets a bit dull, but I've enjoyed short bursts.
Holdfast: Nations At War - Another one that I've not actually played recently, but its entertaining. Bit rough in places, at least the last time I played, but I'd certainly be up for playing again.
