Shogi is Japanese chess, which I learned for the sake of learning, and ended up getting pretty sucked into and quitting because it took a lot of time and was mainly set move memorization. I took my Nintendo DS and started playing again, to the tune of 6 hours or so a day, even playing in the car and on the bus. I thought this was rather antisocial, but no one really commented on it.

twoandtwoisnine möchte ein sozialer Mensch sein und hat mit Shogi wieder aufgehört.
