Oh MAN I played a lot of GunZ. I actually did learn how to kstyle half decently, and the game gets really boring when you do; everyone is invincible most of the time from the block they get during butterfly, and the only loadout you see is dual shotgun. It's basically a game of tag where everyone is zipping around trying to shotgun each other in the back and kills hardly ever happen. I would regularly make new accounts and level back up from 1 just so I could play against people that were using different loadouts :omg:k:
Movement tech is definitely a fun feature in competitive games even when it's unintended, like wavedashing in Melee and bunny hopping in Quake. It's just so funny to me that GunZ caught on because it launched so massively broken and exploitable that the skill ceiling ended up being huge. It was like a contest to see who could out-exploit their opponents. It's the kind of thing I can't really picture happening again, but it was a ton of fun in its heyday.
