Yeah I have a game journal I keep. I originally had it on twitter thinking such a huge site would never go anywhere and wouldnt have any problems. I've since moved it to Mastodon. Everytime I finish a game I writeup a brief toot on my experience and throw in some screenshots.
I started because I was burned out on games and wasn't enjoying anything I played. The journal helped motivate me to finish games so I could share my thoughts, and I found myself really enjoying the hobby. It also helped me budget my time better so I do a lot more of my other hobbies/interests as well now.
