One of the greatest, if not the greatest plat-former on the PlayStation 2.
Story: 8 (An accident turns catastrophic...)
Graphics: 7.5 (During it's time, the graphics were modest and efficient for everything in this title)
Music: 9 (A different tune throughout the world makes everything feel different as well)
Controls: 10 (I never experience any problems, not a single type)
Sound: 8.5 (The majority of the voice work do their part, while Max Casella [Daxter] outshines the rest of the cast; the sounds of several fantastical elements feel right on every place)
The story starts out with Jak and Daxter ignoring the demands of the Green Sage by going to a dangerous island, while unintentionally discovering a plan that risks the destruction of the world, and shortly afterward Daxter tampers (falls into) with a lethal substance known as "Dark Eco", and turns him into an "Ottsel." The duo escape the island, while the Green Sage instructs him to find a Sage capable of reversing the effects of the Dark Eco, and the duo set off to find this "sage", but discover the difficulty of this "discovery". Despite how childish (and typically suspicious) it may seem, it brings upon many interesting and even "happy" elements throughout the game, making it more and more immersible until the end.
The game-play consists of a typical action-plat-former. The jumping and collecting of several items (precursor orbs, power cells and scout flies) are mandatory or optionally required throughout the game, and minor combat is present, yet not even needed in this game, which at times makes things pretty interesting, like the use of Eco elements to use to Jak's advantage, against enemies, and so much that can't really be described by mere words.
I truly love this game, as it is one of the reasons why I even bother playing video games in the first place, and it is a brick in a building that gives me a reason to keep playing more. I couldn't recommend playing this game any further, it is worth being placed, or even an "honorable mention" in anyone's video game collection.
