Vanity items.
The big thing currently (?) is people buying a season pass with about 100 rewards. The more they play, the more they unlock. Be it Skins for their avatar, their weapons, emotes, basically anything that can promote the 'individuality' of a player. If people enjoy the action loop within a game and the 3-5 seconds of actions which they repeat for 8 hours straight... and we can emulate that without becoming an endless feed of doom...
Maybe we should get everyone hooked on a daily Nostr dosage. Like the season/battle pass every time people logon they get rewarded with something.
Should there be achievements/trophies within Nostr for accomplishing things? I'm way overthinking this and the gamification aspect. In MMORPGs like WoW it's very common for people to spend 8-12hours in that world. There's vanity items of course but the best items in the game are those earnt through time and persistence.
Will the unification between something like https://www.onosendai.tech/ , Nostr, Bitcoin and Gaming be the huge leap forward I wonder.
Perhaps nostr:npub1arkn0xxxll4llgy9qxkrncn3vc4l69s0dz8ef3zadykcwe7ax3dqrrh43w could think of a way to entice people to stay in the Nostrverse? (Sorry for @'ing you chief!)
