There are several projects trying to do their own life sim. One that was supposed to be published by Paradox was cancelled recently, shortly before planned release, and to the surprise of the dev team apparently.
This is not an easy genre to develop for, lots of things can go wrong and it might be hard to find a good balance between boring and unmanageable feature creep.
Even Cities Skyline devs had a headstart, they already had a successful transport sim before they tried to fill the smoking crater left by EA SimCity’s explosion.
Europe does, at least for Nintendo e-shop. For some reason Nintendo keeps managing both at the same time. When PEGI (Europe’s own ratings) is totally okay with a game, but Australia has a brain fart and thinks a retro-style shoot’m up with pixellated little spaceships shooting at each other needs to be mature, the game is suspended form the e-shop for both regions, generally for months.
There’s some weird ripple effect going on I think, it goes through an international rating system of which Australia’s one of the biggest member. But the fact still is a game that passes the (mostly) reasonable PEGI can still be removed from the shop if a very stupid butterfly flaps its wings on the other side of the world.
