I mean unlike ASYLUM, at this point L.Depth doesn't really seem necessary to play if you aren't really super invested in experiencing all the lore of the series as the characters and story of it don't seem like they'd have a huge influence on the series overarching story going forward like some in ASYLUM do. No idea about INNOCENT RULES because I'm still waiting for it to be fully translated and so I haven't played it yet.L.Depth
INNOCENT RULES
