Thought I posted this last night (probably sitting open on my home computer), but I also finished Mark of the Ninja. Had quite a bit of fun playing at a leisurely pace and taking a little over 12 hours to get through it. I didn't get everything but had a fairly high completion rate. Generally went for undetected plus lots of dead guards. Probably will fiddle with some of the other costumes. I never had auto-stealth kills, so I'm guessing that was in a costume I didn't put on. Hide + pick up bodies was the only thing I found frustrating. Sometimes I would replay a scene a few times to try to get the guards to kill each other (which I found to be the most amusing way to take them out).
Other than that, I've sunk a somewhat embarrassing amount of time into FTL in the past couple weeks. Recently, I've been playing Dungeon Defenders split-screen with my son.
Since my last post in this thread, I've also finished (and sunk quite a bit of extra time into) Torchlight II. Got my 2d platformer fix by beating Super Meat Boy and VVVVVV. Also played through Jamestown, a couple play throughs of Atom Zombie Smasher, and finished Cthulhu Saves the World. Forgot how much I missed PC gaming.
I sunk quite a few hours into SpaceChem and enjoyed it a lot, but never finished it. I'm a little too much of a perfectionist and some of the later levels are hard to be perfect at. I hope to get back to it sometime, though. Plus, I think I bought some DLC for it.
