My current fixation is A Dark Room. (Like I need more fixations. I'm dripping in them.).
There is something so elegant about this game and its incremental drip of information about its systems to its player, then its exponential explosion of those same systems, matching a similarly slower then rapidly expanding sense of its world.
This may be my game of the year.
If you know nothing about it, you should really check it out. Read my article after you've played it for awhile. It's better to know nothing going in.
