So many things come to mind. A few of the top for me are:
1. Time with my kids. My youngest like to repair, play and compete.
2. The social part of making new friends and getting together to play, repair or compete.
3. The complex machinery of the games offers a wide array of "do it yourself" work at all skill levels. From changing rubbers all thxway to board repair and playfield swaps.
4. Discovering new games that I haven't played. Learning the rules to get better scoring.
