A fighting game (like Street Fighter) but it's all young children, in various schoolyards around the world.

Not a game. Just an API. Simulate a big world and just let it run. Allow others to make clients for the world in different styles, viewpoints, and work different mechanics. But those clients connect to a simulated world.

Whatever it may be, add mayonnaise.

A 3d rpg and the story should be a nobles life that has to get to know his country because his father said so. Then you can decide if you wanna help your underlings or make their lives suffer. The timeframe is up to you

a game where you have to pack your own bag of groceries at a self checkout kiosk without making the scale error out and avoiding direct confrontation with the attendant. and maybe bonus points for ringing up produce as cheaper alternatives.

Please make a spiritual successor to Crimson Skies.

The arcadey air combat, the alternative history air piracy setting, and the gloriously over-the-top voice acting and scripting.

After spending many hours of my childhood playing that game it would make my soul sing to play something like that again.

A puzzle game with simple graphics where you are the reanimated corpse of some environmental activist who was killed by being thrown into a chemical vat and flushed to the river. The forest brings you back to life with the goal of eating ~~billionaires~~ bad people who live in their mansions equiped with bunkers and panic rooms.

Edit for additional thoughts: bonus levels could be something akin to Epstein Island or Davos. Would be nice if "the help" could also get in on the fun, like you crack the safe with their passports and in return they give you the passcode to the safe room.

Detective game where you have to find plausible explenations for paranormal events

"Save the Lemmyverse" - a game where you are a lemming and each level is one Lemmy community, with insider memes and problems unique to that community which you need to fix. It has dialogue-based sequences where you need to investigate what's wrong with the community, and then a random minigame to finish each level.

There are shops where you can spend upvotes to buy stuff.

There are collectible memes scattered around the game and you can post them to c/196 to gain upvote currency.
If you accidentally visit without posting anything new, you lose currency.

I could go on and on with this :D

a traffic engineering game where you have to design different cities as efficiently as possible to allow traffic to flow smoothly to and from various points. different goals can be met for different stages, like: connect zone a to zone b with maximum flow possible, cut pollution in zone c while keeping flow above a certain threshold, make traffic take so long that eventually people will abandon their cars in the middle of the road and start walking to their destination have crashes exist, and cause congestion because of gawkers have a setting for the shittiness of the drivers

Developer skilled enough to make a prototype game in a week... Github account is only 3 weeks old

tetris around a cube where you need to keep up with 4 separate tetris games at once and create a line along the entire circumstance for it to disappear

Another one.

You're a soul reaper. You travel between bubbles that fall through Purgatory. These bubbles are the possible final moments of people's lives, and you can either help them or ignore them. In the end, you need a soul to get to the next Bubble, otherwise you have to brave Purgatory, an infinite black void full of gargantuan, terrifying spirits that consume the bubbles once someone dies.

It's an interesting concept that allows you to spin a lot of beautiful, small stories. Stories of hope, dreams, loss, terror, love.... Lots of freedom. But there needs to be a reason that you eventually start to explore Purgatory ....

I'm just going through old stacks of paper. Yesterday I found around 10 pages of precise game planning I planned (and never made) when I was 12. Use it :D (it's totally possible without a huge game studio and team).
