Often regarded as one of the best JRPGs ever created, Xenogears is heavy handed with its philosophical and religious undertones. Though its complex plot and sci-fi themes wowed millions (and bored others to tears after 80-plus hours of Freudian mumbo-jumbo), it's also revered for its interactive combat system.
During battle, you can attack with a variety of martial arts moves, varying between strong, moderate, and weak strikes. Each requires a certain number of Action Points to use, but by chaining certain combinations of attacks together, you can unlock special moves called Deathblows. Many of the game's battles also take place in Mech form, as most playable characters have access to a giant robot, called a Gear. Here, combo chains work much in the same way as they do in character battles, with AP replaced by a Fuel resource. Whether or not you can comprehend the high-brow narrative, bashing in enemy robots with a giant mech translates to pure unadulterated fun 100 percent of the time.
