Making me feel old if what you guys are saying is considered old school...heres something i posted a while ago:
Full black was 10k standard price. Remember it being such a ridiculous task to find a black battle axe or 2h.
I remember when I first killed Elvarg too, I remember having to keep wiping my palms on my jeans because it was so intense lol.
Castle pking was the shÃt. Pking those guys that always were picking up the chaos runes and using them to add to my pking gear

Having to chase them back and forth up and down ladders was always a challenge to get to them before they logged.
Logging in and out for catch before you go pking

Certing and uncerting your lobbies and swords before/after you pk. Suicide training on Jailguards in draynor, 3 iteming. Being able to walk from Lumb to varrock/edge was so set in your brain that you could do it blindfolded.
Low level pking was always extremely fun. I miss arching behind the fence with my xbow in varrock, and being careful not to go in when an actual melee'r was behind the fence too because you were only 10hp lol.
Making a wine pure, drinking wine then punching the bags in varrock to have a level 13 with r2h. Only 10hp though d: Deathmatches at altar, and chaos altar. r2h, strength ammy, str pot, and swordies.
When pking in style(ie monk robes, wizzy hat, gloves, iron chain) meant risking food spaces.
If you were a 1def pure, you always had to make sure that when you first logged in you had to not kill a low HP NPC because you were defaulted to "controlled" attack style giving you def exp. Making a super quick switch to strength/attack before you kill a monster was always the task at hand and should never have been forgotten.
Botting low level NPCs(cows, monks, chickens) were always the fastest EXP getters if you were a pure.
"How many levels pure are you?" meant how high in levels your HP was in comparison to combat. This meant pures couldn't raise magic, because it gave you a lot of combat levels. A pure always had rune chain, If I look on my old accounts I don't even have any rune plates just chains.
When the most expensive item in the game wasn't more than 200K.
Siiiighh. Sorry, I just nostalgiagasmed my childhood.
