I played Lostword like years ago but I never played Arcadia Record

Never heard much of Arcardia Record outside alleged ZUN's guideline violation when this game is in launch period.
As for Lost world altho It's too much works for me translating touhou from jpnese every days but I played for about 6 months anyway. ...also global server is really kill my mobile gaming enthusiasm by a lunatic publisher who decide to catch up with japanese server by the christmas
conclusion : I might try Arcardia Record for about 7 day or less.
