I’m not reading through all the comments to see if somebody has already mentioned these…
A game where you start out Godlike, superbuffed, maxed stats, best equipment whatever… but to progress through the game you slowly start to give up your gear, quit using your best skills (until they atrophy and are lost/drastically weakened) to end the game as a regular person just doing regular things. The catch would be to wrap a good story around why you’d be giving up all your cool shit.
A FPS that is split between the cutscenes of the warriors talking shit and the generals talking shit and the actual gameplay of you being a random nobody who is just trying to survive. You can’t pick up weapons, because you dont know how to use them or it draws attention and you get attacked directly by the soldiers of both armies. Maybe there’d be NPC’s at the beginning of the levels that you’d sorta be expected to try to keep alive but inevitably they would start to get picked off by cross fire, artillery, tanks, booby traps set by the fighting soldiers, etc.
An RPG where the basic game loop is kinda flipped. Where you’d expect to have random encounters and fights, you’d be able to see the mobs and the interactions would be more of the “Talk” or “Trade” variety but doing things like opening a door or crossing a bridge or equipping a weapon starts a fight. Usually your character would have something wrong with them… so like, going to sleep would leave you with sleep in your eye or groggy and trying to search or open things would start the encounter. Another example, your character’s let gets hurt and now your random encounter is with the cobblestones that you’re trying to walk on to get to the house of healing.
An RPG in the style of like the NES/SNES Final Fantasy games or the Earthbound/Mother series where you’re characters are trying to start a band and the Random Encounters aren’t fights but gigs. You finish the fights by either playing really well a type of music the crowd wants/likes, playing poorly or playing something the crowd doesn’t want/like until they kick you off stage. The goals are things like, getting better equipment, playing notable venues, making a name for yourselves and making it to “The Big Show”.
