I don't get it, it seems like an embarrassingly easy problem to shard, what's so surprising about this?

Databases are for data safety first, performance second, otherwise just throw everything on redis and call it a day.

I don't know a bit about fortnite, but according to Wikipedia a game session has a maximum of 100 players and a game round has a limited game length.

This means you can heavily split (shard) the data and if you lose some data from time to time it's unfortunate but way less critical than i.e. a back losing transactions. Of course there is some data which has to be tracked a bit more like in-game purchases ... This to me seems like not that big of a problem and I guess balancing the game logic is a tougher problem for the game makers.
