Spotted on an Australian girl gaming blog, apparently the Hello Kitty MMORPG is going into full beta (in general? or has it been out for a while and just the english version is beta'ing now?) Since the site proclaims beta is full, go home, I haven't really looked into the details.
If it's anything like Fairyland, another super-cute asian MMORPG that I played for a while, it may be worth poking at briefly as long as it's free-to-play and adorable (these asian mogs tend to be free to play, pay for gold and customisation and stuff) but ultimately it will become endless grind with no point. Cute gets dull when you're standing in one place for hours picking cotton.
