Oh, hey, look at me and my being able to get a copy of SMT: Nocturne!
Turns out it's called Lucifer's Call in Europe for some unknown trademarking reasons, but it is totally mine. And I've been playing it like a complete dumbass, stumbling into a boss fight at least twice without saving. And, yet, so far I've managed to somehow make it through in one piece.
I've been told that the Fairy one gets at the very beginning is very important, and must not be lost in any way, so I'm following this advice.
Also, hmm, the Press Turn mechanic is... interesting. I think I prefer P3 and 4's All-Out Attack, however.
