As a kid, I was absolutely obsessed with subways. Whenever my family and I traveled to a new city, my immediate fixation was not the city’s many attractions but rather the intricate infrastructure linking all these various locales. While my family handled the destinations, I handled everything in-between. I wanted to know the most efficient way to get from point A to B, if there were any loopholes or special conditions necessitating an off-the-beaten-path itinerary, and most of all, I kept tabs on any planned changes regarding the evolving transportation so I could make notes of where to adjust and prioritize for future trips. I never realized it back then, but there was a certain satisfaction to memorizing every station and optimal route and running the simulations in my head that eventually led me down the path of engineering.

Mini Metro is essentially my childhood fascination with subways conceptualized as a video game. It’s super easy to pick up thanks to its minimalist design and intuitive controls; passengers are depicted with geometric symbols headed to corresponding symbolic destinations, distinctly colored subway lines are constructed by dragging your mouse between stops, and you can easily manipulate existing lines without disrupting progress by simply clicking and dragging sections of a line to new stops. At the same time, it can quickly become challenging, but this skill ceiling feels fairly approachable because the game is less about memorizing specific formulas and more about understanding implicit guidelines. For example, having a line that hits every stop in the area sounds appealing, but what’s less appealing is how much more time is subsequently spent traveling and loading/unloading passengers; you can at least somewhat account for this by toggling specific stations as “no-stop” to create express lines. The AI is fairly predictable and will always calculate the shortest path to the corresponding destination, but this also means that there’s real potential for them to overload the capacity of certain stations while in-transit between different lines. Alongside this, the game is great at organically iterating upon its basic formula to escalate difficulty by introducing more stops, altering the shape of stops to create more unique passengers and necessitate different routes, and increase the system’s load with more passengers while forcing the player to juggle their already limited number of lines, cars/carriages, and tunnels/bridges as also dictated with newly unlocked maps. At its core, it’s a game that’s great at subtly teaching players how to recognize bottlenecks and micromanage individual elements to fully understand how minor changes can quickly ripple across the fully intertwined system.

My only real nitpicks are that picking apart subway loops can get a bit annoying since you can only fiddle with one exposed end at a time while in loop form; it’s a minor complaint considering that you can pause the game at any time to more carefully reconstruct lines, but adding extra steps to reconstruct common subway loops is fairly noticeable considering Mini Metro’s elegant interface. Also, I do wish that there was a way to construct slightly longer paths along rivers instead of automatically building across them between certain junctions and using up my already limited supply of tunnels and bridges. Nevertheless, I acknowledge that this last gripe is mostly personal, and I think this game absolutely delivers upon its premise with precise execution. With so many different maps and daily challenges to boot, there’s plenty of content to exhaust within the game, and if one finds the basic experience too stressful or is more interested in sheer experimentation, then they can simply turn to endless and creative modes instead. For an accessible yet deceptively deep management game that gives great bang for your buck, I’d say Mini Metro is a fantastic entry point into the world of optimization simulators that more than holds its own against its more daunting peers.
