There are a lot of classics on this site. I respect that. Some of my personal 'best games evar' are hosted here, much to my delight. Bearing this in mind, Beyond Good and Evil is, without a doubt, the greatest game on this service. All of the fun of brawler with none of the repetition. All of the character of a JRPG with none of the whining exposition. All of the intensity of a stealth game, but crafted within a rich, satisfying context, so that it is challenging, yet rarely ever punishing. Beyond Good and Evil is a stellar experience from the moment you start playing to the bit at the end of the credits that you didn't see coming. Even the credits are superb.
There are few flaws. I can list them for you. The camera, if during combat and in a confined space, can be a bit awkward, as if it is tied to a monkey having a seizure. There are occasional one-shot drones scattered through a couple of levels - they can't see you, but encourage you to stay hidden. There are a few too many plot points left untied by the end of the game, which are intended to be resolved in sequels. These are all the flaws in the game. That is pretty much all you need to worry about.
BG&E is a quality game with a level of fullness and satisfaction that surpasses most of the games you'll ever play. Honestly, it's okay! You can buy this game! Just calmly, fearlessly, scroll up, click download now, then enter your details. You'll be in possession of one of the finest games ever crafted.
