It's fun

Hmm... it's quite rare to see tangled lines connect into a single path. It resembles the tracks of reindeer left on the snowy fields of Hivern. If I follow the route you designed, will I be able to find Stardust Shards?

Creating a subway map is like solving a puzzle where I connect complex spaces and flows according to my will, and it offers the creative fun of designing a virtual city system, so I lose track of time.
