Attendance nitpick
 

Seems like an situation that should be covered by the attendance model. Why was I more excited about this fictional game than the actual fictional fans?

For what it's worth, during that era in real life, I think there were often pennant-clinchers that were played in front of non-sellout crowds.

Although, that said, when the Mets clinched the NL East in real life a year later, they did so in front of a sellout or near-sellout crowd.

You know, I think it depends on whether the pennant is a foregone conclusion. If a team has a 12-game lead and is clinching in the first week of September, then maybe it wont sell out on a Monday night.

But the final weekend of the season when the team has already started selling World Series tickets, and against a 2nd-place team that can still win the pennant if they sweep?

The last game of the previous homestand had 29K attendance, so I suspect that "pennant clinching" events are not part of the current attendance model.

For example, this team drew 49K in Game 7 of this season's World Series

You're probably right.

The game already tracks things that have historically affected attendance...

a) Pennant races

b) Hitting Streaks

c) Pitchers approaching 300 wins

Some things not tracked in-game but that have affected attendance:

d) Hitters approaching single-season HR mark

e) Hitters approaching career HR mark

f) Hitters approaching career hits mark

All of these things could be modeled with a post-facto adjustment to a game's attendance (i.e. selling an additional % of otherwise unsold tickets)
