Everything is way too spread out, and the worthwhile parts are all way too crowded. Everyone shows up hoping to make it big, and scrambles over and uses each other to try to realize their desperate, shallow dreams. The few who aren't there to climb the social ranks might have some fun, but over time they'll grow cold over how impersonal it all feels. Oh, and even if there are purported "fast travel" options, everywhere takes waaay too long to get to.
You encounter countless strangers that you don't treat like real people, which is fine because no one seems to give a shit about you either. Everyone is rudely hustling and competing toward vaguely defined objectives, and everyone seems to be doing better than you. You keep telling yourself you're going to quit on it, and yet you can't. A new map is always too small, and the price is always too damn high. And there are SO MANY bugs.
Your city is bright, colorful, and fun! Safe, unchallenging fun. For children. And much like Nintendo characters, no one actually seems to have a job. Year after year, nothing really changes. It becomes exhaustingly bland. At least it's super easy to get mushrooms.
Everyone is a mover and shaker who relies on planning, angling and luck. You'll often encounter lofty, admirable ambitions that turn out to be a colossal waste of time. And if you're really into this kind of stuff, most people probably find you very boring. It's your ultimate aspiration to be in total control of tiny little people that you do not regard as actual humans.
Extremely difficult to pick up, and extremely confrontational. If you pick a fight with a 14-year-old you're likely to have your ass handed to you. The hardcores swear by their lineage regardless of many objective flaws. All of the characters have stupid voices.
Intermittent pockets of extreme danger and safe zones. Filled with stories of an awful past, and the quiet fear that the bad times may be coming again. At times the environment can be hostile, and you must be equipped with the proper items and bravery to survive.
Built up on classic architecture, yet willing to challenge conservative conventions and bring new ideas to the table. Unfortunately, things are frequently mired with pretense and it can be way too competitive to find a spot in the inner circle. Also these folks also find themselves in a one-sided rivalry with people who tend to forget that they even exist.
This used to be a thing, right?
