I was thinking of requesting something like an anime song themed BGM. I think it'd be really cool, like when you're loafing around in fcity and suddenly some melody started playing.
Either with the voices or just plain music is fine. Oh btw, if the BGMs are like "bounded" to the game or something like changing it will change the image or something of ragnarok, then I can understand.
PS: This is my first RO server so I don't know about the "default" stuff here. Thanks.
