I´ve actually played it on all the servers that are currently available (like Joymax (or whataver it called now), AeriaGames and the korean versions too.) I spent likely most all of my Summers in there, but one day i was actually bored that there were no PvP on the european version, no New events ecc, so i stopped.
It was a good game,IT WAS.
The recent developers (Gameking) seems doing their best to resurrect this game, they held new event in every month, release new dungeon (xuan raid and zhuqi raid) and this sept 6th they will release new dungeon baihumon raid, and they promise to add susanoomon and PvP (kaisergreymon and magnagarurumon is already released)
