This was perhaps the most beautifully crafted jrpg I'll never finish. While the nostalgia hit me like a truck, after just some 8 hours I just felt I had played it all. The graphics and the music may be the very best in the genre, but the gameplay left much to be desired. Time-based inputs are nice (though they do get tiresome after a while), but there's just no substance in the gameplay. Progression is slow af, and I didn't feel there was much to unlock other than higher numbers, which are meh.
I really enjoyed the story. The battle system was fun at first but then didn't really offer much depth or player expression as the game progressed. Maybe that's why you got tired of it?
