Not only that but diablo 2 had such a prolific duping problems of this 1 ring. The ring itself became a currency.

They eventually added a mechanic in game that consumed the rings for something else as a way to remove the rings from game without deleting at will.

I think SOJs became currency and the duping problem made them worthless and moved the currency to high runes? But what they did with the anni quest to get rid of the rest of the SOJs was clever

Oh man, thanks for the nostalgia trip!

GTA Online had a number of methods to quickly rack up unlimited money when it came out. Not really external hacks, just regular old in game glitches were around. I used it to get a bunch of money in game, and rather than breaking anything, it just made it a lot more fun being able to drive whatever car or get whatever I wanted. Calling up a tank is a blast in a game like gta online! I pretty much stopped playing the game when they patched everything and reset the in game economy and made my character broke and boring.

The part hat dupe trick!
