It has Ragnarok aesthetics, but all the music and sound effects will feel very familiar to Granado Espada.
It even has a barracks system and family name that all your characters will have.
Been playing it with an Xbox One controller to get the feel for it. It's a nice game, but at the moment it feels a bit grindy to solo.
Storyline "Boss" fights all feel roughly the same so far.
Mostly I see other people partying up with strangers and doing classic mob grouping to grind after they run out of quests.
