The industry is loaded with them. Many times, sequels don't expand upon an original title all that much. Most of them just add a few new costumes here, a bit more levels there, a couple more abilities here, and voila! Instant sequel.
But, there are certain other sequels that not only improve upon their original titles, they evolve them, making them entirely better experiences. Unfortunately, there aren't many that do. However, these ten do. And anybody who has played the original game in the series can attest to that.
