Mario Kart World, of course, has an open world mode, and much of the interest of an open world racing game is dynamic situations produced by the traffic.
There’s been explorations into where the cars and NPCs come go, and we posted a video on that topic a while back. Sometimes they end up meandering in loops. Sometimes they leave the roads and just go tearing about the landscape. Sometimes cars actually find parking spaces, leave themselves there, and NPCs pop out and start wandering.
Well, similar questions can be asked about the game’s trains (15m). Mr A-Game on Youtube followed them around for a while to see where they come from. He claims to have discovered “how the train system of Mario Kart World works,” but I’m not sure. There appear to be tracks that trains can travel down either way, meaning, there must be some system in place to prevent train to train collisions. He does uncover some strong tendencies of trains to take particular routes though.
OnADock performed their own investigation that also involved boats. (17m)
If I had to guess, I think trains probably aren’t modeled outside far out of sight of active players, that they’re spawned randomly, and that some checks are performed to make sure two trains won’t share the same track. This is a guess, but it would be in line with the impromptu nature of the auto traffic simulation. It’d also mean that the P-Switch missions that rely on trains being in a specific place won’t be disrupted, and that the train can be left behind in the world after the mission without getting in the way of any grand schedule coordinating the trains.
Well, that’s what I think. Maybe I’m wrong. But… maybe I’m right?
