What an interesting direction for the series to take. Going from the "orbal-clockpunk" world of Sky, to the high-tech Crossbell State is a trip, but everything tends to fall into place by Falcom's hand. Zero suffers a bit from "first-game" syndrome in its arc, where the stakes are more often low than they are high, but serves well as an introduction nonetheless. The SSS are an example of a fantastic RPG cast and their dynamic with each other is excellent. Just an incredibly comfy game overall.
