Similarly I've wanted to allocate some amount of time to a creative outlet, which I've neglected for some time. Huge time sink to get something out of it, I feel. I also enjoy variety when it comes to games. That can be chess at times, but not in a dedicated, obsessive sense, just a means to flex my mind a bit with puzzles.

Admittedly, level of challenge in games can vary tremendously. I always like to have one on rotation that is difficult.
