idk how feasible it is to actually work on something like this over a lefftist forum with people that likely live in different countries or parts of the country but i'll elucidate my idea for fun. incoming leftist meme of text.

the basic concept is to make an FPS game that intentionally de-emphasizes graphical fidelity to focus on gameplay. I'm talking like, original DOOM style sprite graphics, where the characters (and maybe vehicles) are 2d rotating images in a relatively low-poly 3d world. I'm a huge nerd for vehicle combat, mechs, and combined arms gameplay, so the end goal would be something just about battlefield scale with relatively large player (or just NPC if multiplayer is unfeasible) counts and enterable vehicles. It seems like a game with primarily 2d sprite graphics for characters and vehicles would make it easier to implement this, any vehicle is just a different first person HUD/cockpit screen with different movement rules and scales and weapons and controls and art assets (lol 'just'). A lot of this is inspired by Terra Nova: Strike Force Centauri (neat game with trash politics, a major planet or system is named 'Thatcher' if that tells you anything), which was an FPS game focusing on power armor pilots, that had the aforementioned sprite graphics in a 3d world. That game had jumping, sprinting, and jetpack boosters, all improvements over DOOM which couldn't even have floors of a level on top of each other. I don't really have any specific ideas for a story or anything yet, just ideas about aesthetics, as I think the game's development should primarily focus on getting gameplay to work well and feel good before anything else, few people play FPS action games primarily for plot. Another inspiration for this is Brigador, which has an amazing pixelated art style for an isometric tank combat game, and while i doubt i could pull off even a fraction of that games style (i read an article about how they did it, it was wile, they had to convert 3d models into 2d lighting data or something), it has activated in me a hunger for similar graphics but in FPS form.

for gameplay specifics, i would focus on movement abilites (like going prone, leaning, crouching, sprinting, jumping, and ledge mantling for both infantry and humanoid mechs; traditional vehicles would handle as expected, depending on whether they are wheeled or tracked or hover or fly), as well as weapon use. i have several ideas for weapon types and which one should be the 'bread and butter' of the setting, but i think playtesting with experimental builds may be necessary to come to final conclusions regarding this. I've always been intrigued by the idea of an FPS that heavily features 'smart guns' like the smart pistol in titanfall, which would force players to focus more on ranging and maneuvering around their opponents sightlines, rather than just the ability to move a crosshair and click on reflex, which is the central skill in most FPS games. another idea would be to focus on laser weapons, which would all be hitscan weapons (they impact instantly where aimed with no ballistic flight time) and could hypothetically allow for unique gameplay like cutting through buildings/doors, reflecting off of reflective surfaces, or unique damage mechanics like needing to keep a continuous laser beam on target for a while to take it out. Another possibility is emphasizing the use of explosive projectiles with large area of effect, like grenade/rocket/missile launchers or artillery guns, which would focus the gameplay on stealth and awareness (different vision modes? zoomable camera pods? drones?) and would encourage units to spread out farther instead of clustering up. I haven't really decided this and perhaps all these weapon types along more conventional weapons would go well together. I also haven't decided how exactly aiming should work, whether it should be classic FPS style with a immobile (or mostly immobile) crosshair in the middle of the screen, where the screen view is moved with the mouse to change the aim point, or whether more old school RPG controls where keys control both turning and strafing movement as well as angling up/down, and the mouse is used to move an aiming cursor on screen freely, or even to interact with cockpit/HUD elements like periscope covers or light switches or vision modes, etc. Maybe different schemes would be ideal for different classes of playable character/object type (whether infantry or vehicle), or could be separate toggle-able modes for everything.

theres a lot of more specific ideas floating around in my head but this is my attempt at summarizing. i think multiplayer and networking would probably be the hardest task to achieve, with enemy and friendly AI being a close second, and even more mundane parts of the game would likely take a team to accomplish. i could probably do a bunch of the sprite art myself, idk anything about 3d graphics and lighting and animations though. i've dabbled in blender and flash to not much avail. I don't know how much easier game dev has become with new programs and computers, i'm vaguely aware of how much work and people it took to make the games i've referred to, and i'm sure it would be much harder than anticipated especially for an indie dev or even group without much experience.
