What major MMOs had a Krono like system before EQ/All access games? And don’t say WoW because it came 2 years later. RMT business was estimated around 800 million for online games....in 2005. EQII experimented with a real money auction server as a way to profit off it. Then next came Krono to literally per their advertising “spend real money for items/platinum”. Now do you honestly think they expected the sellers would never in turn then RMT? They are not that stupid....the choice was join the RMT market or lose hundreds of millions in revenue.
