Grim Fandango is one such game. I love the characters, dialogue, music, and visuals. Most of the puzzles are a pain and lack context, though, and I'm not interested in going through them again.
Also, despite loving the Musou series, I can't go back to my favorite Warriors games (Samurai Warriors 1 and Dynasty Warriors 3) because of the vast gameplay improvements of the later ones. The newer ones are so much more faster, smoother, and overall play better.
