A couple things I would want is franchise records being a part of the RTTS player milestones. While the milestones e.g.(200 H.R. tracker 100 Win Tracker) is nice, I do think it would be cool to be like my RTTS is second on the Orioles for career hits, or when I retire it says where I stack up in terms of all time wins in franchise or MLB history. If I'm the all time base-stealer in Orioles history that would be cool to know in RTTS. Or if you break a single season record for a franchise.
. Also adding career playoff statistics would be nice. Also the retirement process is very underwhelming, like after 20 years of playing for one club and you only get a couple clubhouse conversations. Month by month stat tracker that the user can view for all of their stats to get a better feel of how they are month to month.
Also allowing the player to set his own goals for the year. It would be cool to say my goal is to hit 20 HR's and 20 2B's this year, and receive an attribute increase for reaching those goals.
