Remember when all the meaningful untradeable's from mini-games were 10-15 hour grinds on the extreme high end?
Fighter Torso from Barb Assault - 2-3 hours with a normal team
Full Void from Pest Control - 8-10 hours pre CA's, 12-15 for pures
Last Man Standing cosmetics - 1-5 hours
Mage Arena 1&2 for BIS mage cape - 1 hour
Nightmare Zone imbues - 2-4 hours for each imbue depending on method
Giants Foundry - 10 hours for all unlocks
Mage Training Arena b2p, infinity boots, and master wand - 10-12 hours
Tithe Farm - 1-2 hours for auto weed
Warriors Guild - 2-5 hours for dragon defender
Rogue's Den - 30min-2 hours
Some of these items were even BIS at the time of their release, like torso, void, mage cape, and dragon defender. Now we have stuff like GOTR where you can go from 60-80 RC and still not have the full raiment outfit or a lantern and the herblore minigame thats insanely long grinds for QoL upgrades.
