Currently started (at least somewhat) working on a submarine simulation/strategy game. I want it to be as lightweight as possible so it runs on as many systems as possible. Probably a lot of 2D graphics wherever graphics are necessary but a lot of focus will be on sensors and calculations. I want it to be Dieselpunkish with a technology tree between 1910s and 1960s but without featuring real world countries or submarines and no nuclear technology. The simulation of individual ships should be in depth in a dwarf fortress kind of way and I want realistic sound propagation. I’ll try to incorporate submarine design as well.

Global Eden

Objective: plant the 🌎🌍 globe

Where (in simulation?) You can build nurseries, build drones to send plants to your local surroundings, link up with other druids across the Earth, collect & add reports on mycelium, bacterial & insect cohabitations, explore the woodwidewebs, develop food & energy generation, waste remediation for all buildings (every plot of land on the planet shall (should) contribute to global wealth). Restore & progress balance of life from this dismal current dystopian quest for blood oil steel and waste. Make this planet a better vacation spot than Risa in the closest 1000 galaxies. A happy Ent-friendly planet.

Understanding local Flora & fungii for food, dress, & medication (open source libraries & communities at every forest!)

I love to see more use of tech towards global wealth & unity. Good air & water, good food, good communities, great forests, good travels... These are elements of global wealth. Money and marketing have dwindling use & tax us of great creativity (another lovely element of global wealth) and energies. Building & sharing abilities are priceless.

Gratitude & celebration daily.

An eagle on the hunt simulator. Visualize the air currents for gliding, some kind of zoom and enhance to find prey, then guide the dive and extend claws at the right moment to refill the hunger meter.

I was talking about this just the other day as a joke.

I would make "Car Simulator." It would simulate driving and working on a car exceptionally well. But the game itself would be basically Grand Theft Auto, just with much more realistic car control, modification and physics.

Another, serious idea, I've been kicking around a while but am unsure how to actually do it is a game that captures the insanity of solving fictional problems with fictional solutions on Star Trek. Like a nebula is sapping energy from your ship, so you reconfigure the deflector to emit a neutron pulse or something. It would simulate science itself and create random elements and physics that the player would have to learn, understand, and can exploit. The key is that it's always new and different forcing every player, every new game to be creative in coming up with solutions to the random problem with equally random tools to promote critical thinking skills. I'm just not sure how to gamify "the scientific method" itself or I'd be actively working on making this a reality.

Probably just an improved version of EmuVR. Essentially it allows you to emulate games in a VR bedroom. It is limited to RetroArch systems but it would be really neat if I could smoothly play modern consoles or PC games with it.

Even if it was a hacked together kind of way like using a capture card and something like XLink Kai to play together with someone else.

I'm not sure if this is what you meant OP. I just like the idea of playing video games in a simulated room.

Other than that maybe a Blockbuster owner? Recommending people movies and watching segments of films on the displays mounted to the roof sounds nice.

Fucking

I always wanted to try a world simulator based around mana flows. Trying to create a set of fictional rules that generated a functioning world seems fun.

The two I want are already made. Goat Simulator and Great Lakes Simulator.

I'd like to create a sim so immersive that it can't be distinguished from reality. Anybody who displays authoritarian tendencies would be forced to spend the rest of their lives playing that game, where they can be a bootlicker or a dictator without hurting anybody else.

Reboot Steel Battalion, the only real mech simulator.

World of World of Warcraft

Memelord Simulator

Walking in a forest simulator, it'll literally bw just that, a game where you walk in a forest with extremely realistic graphics and expertly crafted ambiance and sounds, would be the perfect game for me to relax with
