I'd love for either Dwarf Fortress to eventually have some sort of spectation god mode along with more accessibility, or for something else to eventually get close to the level of depth that has. (which might never happen, but at least something with enough depth that it feels like a unique experience on every fresh generated world) This "game" easily kept me interested an entire afternoon and would be interested in where it's headed. It's definitely not something I'd consider to be a standard "game", but I'd love for more developers to attempt something in the "micro to macro world simulation sandbox" department. Only problem is, as a game developer myself, I don't know if there's a market for it like there was for the new Idle games that appeared lately...
Edit: thinking about it some more, I feel like this is something that's finally dawning on me now. There's been many times before where I imagined how cool it'd be for there to be these huge "worlds" or universes, that work like a world simulation... but instead of going for realism they go for a gamified, fantastic ecosystem that attempts to allow for some intense encounters, stories, events, stuff you'd see in an open world action rpg, but in god sim mode. Galimulator is interesting because it also wants to be a game, so it includes the ability to "take control" which could be really interesting for future world simulators, because at any point in the sim, you could make it feel like a game.
Anyways, the point I want to make here is, that concept hasn't been done enough yet. I think there's real potential there. Like, a lot of potential. The reason why I see that in a game like this is because unlike a lot of other god or sim games, this is tied to an actual functioning game with actual, fun mechanics. The Sims without the big picture? Just people living their usual social lives. Spore without the big picture? animals being animals. 99% of the "X Simulator 20XX" games without the big picture? You are basically driving something or doing handiwork. Yeah, we need more world sim games that are actually based on a large scale "game" with deep mechanics and extremely high amounts of emerging ones as well. Epic battle simulator is too simple (just war), and yet this game doesn't even need 3d graphics and it already shows more potential. I won't be making anything on any scale anytime soon though, I'm busy on a 2-man indie team making something else. I also have a tendency to type large essays on the internet as can be seen here.
