I like how all the games tie into each other and how you have made a way to bring them all together making this story even better, I read Serenity first before starting this but I'm looking forward to how far the story goes and the interactions between all three
same, i also played serenity first, and gave it like maybe 6-7/10. and i'm not really much of a fan of 'tie in's (its kinda like breaking the 4th wall), but the way Last Human handles the cameo appearances without breaking the 4th wall is kinda unique (even kinda making yourself a cross-over character (in fact i LOLd when rin said "he even has the same name", cos like, yeah, i namechange to Ghryst in every game i possibly can), and it boosts the score of both games simply with the way its done.
