Resident Evil 2 – 1998
Some sequels build only slightly on what came before. Other follow-ups, like RE2, take everything and improve it the whole shebang in one giant leap forward. Almost every part of this sequel is an improvement over the first. Visually more impressive, it also features more scares, better puzzles, and more diverse areas to explore. Not to mention the changing scenarios that you can play through, giving the game a ton of replayability. There are very good reasons this classic was a huge hit at the time.
