RO2 was a failure when it was FIRST released. The team behind it got kicked fomr the company afaik and then formed Cykan Entertainment (developer of LO).
Later on RO2 got a revamp and was completely changed.
I played it for some time...and was really disappointed.
Its nothing more then a generic MMO with the name "Ragnarok" attached....it sux tbh
And I played RO(1) for 8 years...so its not like I hate Ragnarok in general or something.
