X-COM’s magic is how it makes the war to defend Earth from a vastly superior alien invasion force feel so intensely personal, even with its extremely dated (but expressive) graphics and spreadsheet-like interface. Part of this comes from the way that every decision you make, from where on the globe you place your bases, to which alien technology to research, to whether to spend your soldier’s last few time units to reload his weapon, crouch, or take a Hail Mary shot at a distant alien, has enormously high stakes. Choose right, and your team of alien hunters will gain a leg up on the battlefield from advanced weapons (like the guided Blaster Launcher missiles), armor, or tactical positioning; choose poorly and literally everyone could be slaughtered – or worse, transformed into drooling zombies to serve as incubators for horrific Chryssalids.
While some would vote Final Fantasy VI the better game, 1997's Final Fantasy VII is arguably the bolder one in this anything-but-final roleplaying series. Laying complex polygonal graphics over beautiful pre-rendered backgrounds, Japanese developer Squaresoft took advantage of the PlayStation’s compact-disc drive to craft an experience Sony rival Nintendo—who’d rejected Sony’s pitch for a disc-based add-on to the Super Nintendo—simply couldn’t. The operatic, labyrinthine and often wonderfully weird tale of ecologically minded heroes out to save their “living” planet from corporate energy raiders proved the most popular in the series, selling over 10 million copies worldwide and prompting perennial cries for a remake (that's finally happening).
The original Fable, while very very good, never quite lived up to co-creator Peter Molyneux's lofty "plant an acorn and it will grow into a tree over the course of the game" promises. Fable 2, however, fulfilled an amazing amount of this charming, decidedly British-humored action-adventure. The world of Albion came alive on the Xbox 360, while Fable 2 was also one of the first games to give you a full-time canine companion. The dog was, in gameplay terms, rather straightforward, but for many players, the pooch tugged on your heartstrings and made you care about him/her in a way that you typically wouldn't above the average human or fantasy-pet RPG. Solid combat, a multiple-choice ending, great music and world-building, and a deft balance of action, adventure, and role-playing helped make Fable 2 both the pinnacle of the series and one of the finest bits of escapist fantasy ever coded.
Still, the highlight of StarCraft is easily its multiplayer. Few gaming moments are as satisfying as defending your base against a Zerg rush as the Protoss or successfully sending in a fleet of Terran to decimate an enemy's base. StarCraft is still played competitively in parts of the world, making it remain relevant for longer than almost any other video game in existence. There's a reason too. It's because the gameplay is so expertly crafted and balanced that players can continually go head to head with a different result each time. It's those near losses and photo finish victories that keep you coming back and have kept the series alive all these years.
