On weekends I've been playing Torchlight 2 and Orcs Must Die 2 with friends. Both are a great time in co-op, though I wish I could respec my TL2 Embermage (without having to cheat, that is) given that I made a number of questionable decisions early on when I hadn't a clue what I was doing. Ultimately I don't think the damage is really that severe, but my points are more spread around than is probably optimal. Still, fun little game, for all that it feels slightly "flatter" than the original for reasons I can't pin down.
In single player, I made the mistake of starting Fallout: New Vegas: Dead Money and it very nearly killed my 150+ hour game dead. What an absolutely awful expansion/DLC/thing. Timed pixel hunts that instakill you on failure, obnoxious enemies, dull environment, and constantly eroding health (which is a problem when you've turned off food healing). Blech, misery, and neither the characters nor plot remotely seem to justify the pain of dragging oneself through it. I got a little ways in, playing shorter and shorter sessions each time, then realized this dreck was killing any enthusiasm to play a game I'd been greatly enjoying until I started it. Save reverted, all is well. Tell me the other DLC's are better, please!
