59. Started with the board game in 1974 - my first team was the '73 San Diego Padres. Played for about 6 years until I went to college. Picked up the online game in 2004 (back when Barry Bonds' card was named Y.A.), and have played ever since.
Would be nice if the powers that be would give me credit for all the games I played before 2010, though.
Nowadays I play mostly ATG and the 20XX seasonal Keeper leagues, and this game helped me navigate the pandemic and quarantine without much difficulty, so I'm grateful for that.
