Another pretty cool story is the one of GunZ, an old TPS online where what was originally an exploit became so popularized that eventually replaced the actual core gameplay.

It was born as an arena shooter with guns, shotguns, rifles, knives, katanas and some Matrix style movements such as wall runs, doublejumps etc, very cool concept.

However the whole game physics was tied to your FPS and that allowed for some janky stuff, said janky stuff eventually evolved into an entire different style of gameplay called KStyle (named after koreans who discovered and popularized it.

Stuff like swapping weapons between katana and shotgun at precise frames allowed you to move faster, jump multiple times, do infinite double jumps up walls and stuff like that, so you’d see people flying around waving their swords like butterflies and shotgunning your face, it was honestly very fun and hilarious and eventually it was just so weird, original and better than playing the intended way that it just replaced the gameplay altoghether.

I remember practicing a lot and being able to pull off a couple of the moves but due to my crap PC and connection at the time I was never able to pull off the more advanced stuff
