I play the Basic game, but use the available options like Optional Pitching, Advanced Fielding and Pitcher Fatigue. For me, they each add excellent strategic realism. I play Solitaire games, usually one a day. You can also set up any specific game to be played on Autoplay, but I personally prefer to roll them myself. So, if you want, you can easily pick and choose which games to play yourself (ie. Red Sox or Royals). You can also play just the AL games, if you want. And even if you play a game on Autoplay, you can always review the boxscore afterward.
I would STRONGLY recommend buying the Replay Unlock feature. Well worth the $25.
Stats are quickly and easily saved after each game in Collections. Again… highly recommend doing that. The level of stat-keeping, by individual or team, is exceptional. The only issue I find is that, once every ten games or so, an earned/unearned run is tabulated incorrectly (usually after a Passed Ball, or an Error followed by a Fielder’s Choice). But that’s a pretty minor thing.
Good luck and have fun with whatever you decide.
