Eternal Senia is one weird RPG Maker game, I literally just played it because it was free on steam, and it looked cool.
With a pretty unique combat mechanic (I've never seen it before, but I'm not as well versed in RPGs as I should), it shouldn't take you more than 4 hours to beat it, since there's no need for grinding, and you are always pretty up to date with your enemies, even on new areas and dungeons.
Story is surprisingly engaging, you genuinelly care for Senia and Magaletam and hope for the best (well...), the fairy is kinda boring tho. Not a remarkable experience overall, but a fun one for what it lasted.
