I got this idea of making an mmo that uses meshtastic devices to play. The core gameplay would simply be trading random token and phrases and lore could be part of token.
Like their could be a token called pile or 100 gold coins and their could be a description tag saying "they're all chocolate coins".
The idea is to keep the game simple and robust so that future games can build on top of it.
Part 2 could be centralization/federalization of these games. Basically a central server could be used to track all accounts and transactions if one player allows cellular or has a wifi connection somewhere in the network then mqtt function can facilitate communication to the game server of course these servers can form a federated system where they respect the ledgers of other servers.
Meshtastic games could be pokemon go style games
The bandaid fix would be to Carry an umbrella for shade.
But if you want to go the city route, best to find a committee that works on maintaining parks or makes the city look beautiful and talk to them. Committee could either take action and plant trees or lobby the council. They could also say no, but if it works then youre on the fastest route.
Cities also city managers/staff so you can contact them and see if they can plant trees
