The word 'duh' comes to mind...
This world, and especially the scifi-action-fantasy genres, are run by marketing. There will be a game, shirts, mugs, hats, posters, cereal, toothbrushes, soda cans, lunchables, underwear, ice cream, sheets, pillowcases, toys, posters, kids meals, batteries, lunchboxes...
...and watermelons.
There will not, however, be MLB bases, hehe.
