I did not grow up with the Saturn (or the Dreamcast), so I was kinda looking forward to playing this game for the first time. I honestly did not expect much from the gameplay going into it. I committed to getting all the A-ranks and achievements, and I ended up having a lot of fun (and some frustration) doing it.
First of all, I was suprised with the game's soundtrack and sound design. I absolutely love the soundtrack and have been listening to it all week. NiGHTS' character design is amazing, and although the 3-D cutscenes are looking dated, I had to remind myself that this game came out in 1996. All things considered, I'm pretty impressed by this game, and there's no denying that the ending, with the credits and the song, definitely put a little tear in my eye. They also included some unlockable goodies (cutscenes, artwork, an interview with the creator, and a different game mode which is mostly a reskin).
Aftering experiencing NiGHTS into dreams, I definitely wish I had grown up with this game. If you're into the SEGA style of games or story-telling (like Sonic Adventure stuff), then you might give this one a try.
