SAN FRANCISCO, Aug 24 — Sequels are not always as good as the original, and this applies to both film and game series.

However, not all sequels are inflicted by the terrible twos, and GameTrailers present a list of the best game sequels with a quirky difference: All the sequels must have ‘2’ in the title.

The list features sequels from different genres and generations, ranging from the classic fighting game Street Fighter 2, action horror Resident Evil 2, to sci-fi roleplaying game Mass Effects 2.

This screenshot from the GameTrailers video shows a character from Mass Effects 2, considered one of the best sequels in gaming history.
