I played a bit of Nights when I was young, and loved it. With the announcement of Journey of Dreams, I was skeptical if the love for Nights (for me and in general) was based almost entirely on nostalgia.
So I decided to give the game a another go a couple weeks ago. It was my first time playing past the first stage (I only played the instore demo years ago). I ended up playing through the game several times, and formed a new, better informed opinion of the game. Nights into Dreams is still a fantastic game, and deserves the praise and its place in gaming history. With the fantasy setting of dreams, a touch of childhood innocence, and strangely addictive gameplay, I think the game is still a unique and rewarding gaming experience even today.
A word of caution though. For those that have never played Nights, the gameplay boils down to a 2D time/score attack game. The goal is to link together as many actions as possible (collect spheres or fly through rings) before the timer runs out. Probably not for everyone.
