Do you remember Kitsu Saga? it been great game with very good skill design (not ordinary 1-9 dps buttons but real skills that can change whole combat). Sadly it failed because cheats, auto bot & auto pot (many people disliked it decide not even try game) and requirement to spend tons cash on purple gears.

Game even died in TW server and no more content updates for it anymore (Tho they still get new events).

Few years after X-Legend released Kitsu Saga they decided to release second Chinese style mmo - Legendary Heroes Online that become not popular and never been released on west market.
