Oh I wasn't meaning to imply other games DON'T have character development and such, but the RPG genre is what's known for giving each character screen time and meaning. Arcade style games like PacMan or something rarely do it.
It isn't a required thing, but it makes it easier to care about what's going on, when you can relate to who you're playing as and the other characters they interact with. Below that would be a quirky or humorous cast, like Puyo Puyo or something, where there's really not a whole lot of depth to the characters, but the silly antics in the stories get you curious on what happens next. Below that still would be games that barely go into the characters at all, and so interest entirely falls on how appealing the gameplay is.
If you're into a good, fun, and competitive puzzle game series, try all the Puyo Puyo games, lol. Tsu (2) is the standard, and Fever starts the Sega acquisition phase.
