Anybody who is a fan of classics such as the Zelda series, RARE's platformers, and other action adventure games should definitely pick this title up! It is very engaging, with puzzles that are difficult yet manageable. There are many side-quests for pearls, similar to RARE's Banana's in DK64 or Mario 64's "stars"; they allow you to progress at certain points. Yet in reality, this game is a spiritual successor to the N64 Zelda games, but it doesn't provide an enormous inventory or all-out attempts at being epic. Regardless, it is very pleasant; they put the save points (or in game lingo, "mdisc readers") in the perfect spots. Similarly to Nintendo's classic title, it is based around puzzles and struggles in large dungeon settings with a minor yet ominous plot.
That said, the post-modern, alien environment is enticing, the side quests and other fillers allow you to regain your focus, and the sheer unique artwork and mechanics are amazing.
Note: Console gamers, be prepared to use your mouse and keyboard. USB Gamepads are NOT supported in this title!
