Bias notwithstanding, I honestly think that Sonic & All Stars Racing Transformed is a much better kart racer than the recent Mario Kart games.
Don’t get me wrong, Mario Kart 8 Deluxe is a great game, but Racing Transformed is just a lot better in terms of content, character variety, and most of all… balance! The difficulty and items are absolutely perfect.
Moreover, the transformed “gimmick” is utilized in such a unique and fun way while Mario Kart 8 just seems to have them there for flair and small tweaks.
back in his Sonic Drift days Sonic hated cars, he’s warmed up to them
considerably. The cars in Sonic Drift were more like go-karts, which
meant they were slow and boring to Sonic. When All-Stars Racing came
around with actual sports cars and more dynamic and dangerous tracks,
Sonic had a lot more fun. It was when Transformed rolled around and
Sonic found himself in a car that was not only faster still but could
transform into a plane (a vehicle he actually likes to drive) and even
allow him to safely travel through water (something he always dreads), he
actually found it quite difficult to set his feet back on the ground.
