I do not have a girlfriend, but the girl I've been seeing lately doesn't play. I've seen plenty of couples out playing together, though.
Went out to shelby farms (massive park in Memphis) today. I'd say 90% of the 100 or so people around me were playing.
I play a basketball simulation that does the same thing, so you know. I actually think baseball is potentially the most fun game of the "crunching numbers and spitting out fictional results" type, but I don't really watch baseball in real life so I haven't gotten into those types of games (yet)
Last season I bought three underpriced groundball pitchers to put with the best defensive SS in baseball (Andrelton Simmons). Team went to the playoffs with the lowest payroll.
