Fornite as a free game, picked up a huge amount of players in a very short time frame.
In the process hurting competitors.
But now with declining revenue, the idea of going crypto was abandoned in under a week, when the Merch shop started then stopped taking Monero.
If in game rewards were crypto then it would move Fortnite into the new blockchain world, and perhaps join Tron in a growth phase.
Time will tell.
