Unlike its contemporaries, which incorporated more simulator-esque aspects into their design with indepth skating mechanics that sought to emulate their real-life mechanics, Jet Set Radio is at heart an arcade game. It plays fast and loose with the concept of inline skating, even automating aspects like grind tricks to further simplify the controls.
It doesn't lose any difficulty as a result, and this is a game that demands
you learn how to play it.
This isn't the best port. Graphical glitches objects popping-in are the norm, bugs are everywhere (I encountered a particularly annoying one where my game refused to save until I just gave up and reinstalled it), and the new tutorial gives vague and in one occasion flat-out wrong information required to complete it - as well as skipping over integral parts of the gameplay such as wallride jumping.
It's nearly unplayable with a traditional keyboard and mouse scheme, there's no level select for retrying story missions, there's no retry level in the game itself (you simply have to exit back to the hub to retry a level), and the game doesn't display the requirements for high rankings or even how scoring works.
Despite all this - and despite it being really important that you know all this before purchasing - I absolutely recommend playing this game. That wonderful experience of mastering mechanics you'll initially suck at, learning the levels inside and out, the famous OST and the sheer amount of style that this game exudes make this a game worth more than just buying, but a game that's worth getting pretty bloody intimate with.
So get with it, so you too can understand UNDERSTAND, UNDERSTAND UNDERSTAND, UNDERSTAND UNDERSTAND THE CONCEPT OF LOVE.
