I do at least 1 chapter a week unless there are special circumstances (Skyrim being one of them) since Medaka is the do it now type. After that, depending on how I feel, I might do 1-5 chapters of Kamisama Dolls. I had a goal of doing all 1000 pages of Kamisama Dolls to catch up, but after Skyrim (132 hours gone in a month, 90 in the first week) and a few other games that time has vanished.
Also Civ 5 isn't a tank game, it's more or less a game about building a civilization from the dawn of civilization to 2050. It's a turn based strategy game, but it feels like it moves a lot more than other turn based games I've played. Now if I could actually sit down and go through a full campaign on Shogun Total War 2, I'd feel really accomplished (another 20-30 hours of my life...)
