Old School RuneScape is unique among MMOs for too many reasons to list here, but a big one is its variety of account types. You have normal, unrestricted accounts and then multiple versions of Ironmen with special limitations. Ironmen can't trade items at all, Group Ironmen trade items only with their teammates, and Hardcore Ironmen lose their status after a single death. For my money, the most difficult account type would be an Ultimate Ironman since they can't trade or bank items, meaning they carry all their valuables at all times (outside of a few workarounds) in the same 28 inventory slots.
Unsatisfied with what's already regarded as a brutal game mode, OSRS player Schnoblin decided to max out arguably the most tedious skill in the game in possibly the worst way imaginable for an Ultimate Ironman. It took them three years, and now that they've done it, their advice is withering: "Maybe don't do this."
