Walking up the road to Lumbridge to Varrock and always getting killed by the mages outside of Varrock.
Chopping Yew trees in Seers, talking to people, and then selling them in "bank sales" at the crowded bank.
Generally, all the crowded banks where we used to sell things by spamming it out.
"Getting drunk" with my friends at the Varrock pub.
Getting hacked for a few hundred k, feel like I lost my whole bank, and then getting it back by begging people.
When I started RuneScape, my first moneymaking method was collecting coins killing at the manhouse at Falador. Then moved onto Guards.
The first clans I ever joined before going into the off-site clan world and WG, Glory of Saradomin, and then starting my own RSB clan, Soldiers of Glory.
Pking with my irl friends (how I got into RS) in the wildy, trapping people at the dark castle level 13-15 wildy. 3-4 of us would literally be rooms away in a house and adventure together.
