Put all thoughts of Mario Kart clones to rest – Sega's latest on-wheels outing for the spiky blue blur really deserves to be judged on its own merits. While the core formula of zooming around colourful locales, collecting power-ups and hitting boost panels is here in full force, All-Stars Racing...

In the rare instances where a developer invents a new and interesting genre, or even alters an existing genre so much that it becomes a genuine offshoot, it's only a matter of time before another team steals the limelight.

Brilliant rental game for 4 friends to play if you don't own a Wii and Mario kart. Next best thing really.

How would you follow up ? Some companies would sit back and release basically the same game for the next ten years or so. Not SEGA, though. SEGA and developer Sumo Digital go back to that already great racer, rip up the formula, and make something wildly new and fresh and undoubtedly better.

Nostalgia is a powerful thing. It should be made absolutely clear that I am a big SEGA fan, therefore the nostalgia level available from this game to me is vast. As luck would have it, Sonic Transformed goes above and beyond, delving through many more nooks and crannies of SEGA's history than you...

Solid and tight driving mechanics

- Online and general glitchiness issues

A great mario-kart like for xbox 360!

The original Sonic & Allstars racing was a brilliant game that for me came out of nowhere. I assumed it would be a bad kart game but instead I got a high quality piece of software with hours of fun.

It's not really a mario kart clone but it has quite a variety of crazy tracks that go all over the place; Tracks are constantly changing every lap

Not sure if it's my system or the game but the game constantly freezes up and will require you to hard reset; I updated to the latest patch and even tried to install the game to the hard drive but the game will play for a couple of races but then freezes up all the sudden.

A superior Mario Kart clone and certainly the best Sega has ever produced, especially in terms of the teary-eyed nostalgia inspired by its endless retro cameos.

A fun, nuanced racer that isn't a straight copy of Nintendo's formula; Superior range of single-player modes and excellent graphics and music; Fan service is off the scale

Neither the driving nor the level design is as tight or focused as Mario Kart, with the water-based action feeling particularly sloppy; Uninspired weapon designs

' Whenever Sega has released a mascot-fueled game, such as Sega Superstar Tennis, comparisons have inevitably been drawn to its Nintendo-developed counterpart. But Sonic & All-Stars Racing Transformed is far from a poor man's Mario Kart.

Controlling the crazy vehicles feels great; Creative and varied track design that changes mid-race; Transformed vehicles feel significantly different

Certain modes and challenges are completely broken; Can feel slow at times when not boosting; Danica Patrick is out of place
