Ma Lin was thinking up ways to make his gameplay more fun. In today's society, everyone was brainstorming for more and better ways to play and share them with others.
Adventure World games were especially popular; as soon as the game started, players could be teleported to a real little world where they could experience all sorts of gameplay provided by the creators.
"Banana Samurai" was one that teleported all players to the same Nog Continent, while other games didn't have such strong spatial teleportation capabilities.
Generally, players from the same city were teleported to the same adventure area, and everyone could play together.
The biggest advantage was convenience; turning on the game would complete the teleportation. Did this teleportation not require any cost? It did, but the income from the game was enough to cover these costs.
Thus, every city would have its own Adventure World game, specifically serving that city.
