I BELIEVE the box scores for All Star and World Series are stored with different numbers. It MIGHT not always be the same, but I do believe they are numbered differently. I have some recollection of that. Easy enough to check in the almanac if you're saving all box scores.
I did come up with another idea, but I don't think it's remotely feasible.
Like on the Catobase pages, at the bottom of each player page, there's a list of links to similar players, stat wise. I was simming a season tonight and was looking at the league leaders. In hits, HR and RBI, there was one player in each league holding all 3 records for that season. I started to picture these two rivals, and was thinking of some way of kinda "visualising" that. So maybe at the end of every season, like you have the draft picks, also have the league leaders easily accessible, so you can easily pull up the pages of the players who, say, got the RBI title in their respective leagues or divisions.
I've mentioned so much in here now, I don't even remember if I'm repeating myself anymore, but where you have like the Cy Young, MVP etc... More buttons
So you can pull up, say, the top 10 HR hitters of all time etc...
I'm rambling. I need sleep
