Board Game Geek (BGG) is a great site, which I use daily (sometimes more throughout the day) to keep track of the games I own, the games I play and just to see info about a game, mostly before buying but also before playing.
The site has grown big, even when I started some years ago. Recently it got a makeover, and trying to adapt more to mobile devices.
To celebrate the 20th anniversary (20th January 2020), we were a big group of people contributing to a small video to say congratulations. You can watch it here – I’m towards the end 🙂
