So...you know how a lot of RPGs tend to throw in random sports minigames for the purposes of world building? Then this is usually used for maximum tragedy when an OP minigame character dies later?
We need to be able to assign agents to basketball teams, is what I'm saying. They could all compete while training, and then it could be that much more tragic to come back from a mission, only to see that George the Xenoslayer isn't there to win his season trophy anymore.
Just saying, you know you want this. (maybe they can have a champ medal?)
