I knew I was gonna have fun when this game loads to main menu and that awesome song starts up : "Riders of the Storm"!
The game itself plays smoothly, the graphics are good (though the colors seem a bit dull/muted), the controls are intuitive (hint: press the Start button at a shop or event to enter it), and the roads/traffic scene can be described in one word: chaos! But fun kind of chaos, as there are lots of players online, that's cool!
NFSU2 is excellent (I remember completing it on PC, it seems like ages ago), though I liked the 2005's MFS Most Wanted, which is a masterpiece.
I hope NFSMW can be played on browser soon, now that we are in the AI era.
Edit: Found a webport of NFSMW, but it is somewhat laggy on mobile browser, but it looks to be playable on a PC browser.
