Actually, I've never liked Mario Kart very much. Double Dash was a lot of fun, and the Wii one held some interest because it was a unique control for a kart racer, but the MK games are pretty god damn generic otherwise, and have major balance issues. I mean really, after all this time, they're still doing blue shells. Red shells are annoying enough, but "Hey, you're in the lead, so you lose" weapons? Come on. The Mario characters are a pretty limited cast when there's such a good Nintendo catalog to draw from, the levels are all so damn generic. I know Mario isn't a game that's loaded with iconic level designs but "Here's a snow level, here's a desert level, here's a city for some reason" is bullshit even if the track is Yoshi shaped and NOTHING HAPPENS. They're static visually and tracktually (fuck you it's a word now). The point is, Mario Kart is boring and never takes chances. Even though it had a great game (or two) in there, it's stale as fuck. Sonic All Stars Racing Transformed is the opposite of that. It's really fast, the characters and level designs are not only diverse, but true to source (which is really impressive given that a lot of the sources are old 2D things like Shinobi levels). Also because riding around the same track three times in a row in a kart for 5 minutes gets boring, 3 fucking vehicles, levels that dynamically change through the race, and weapons that are all balanced and do interesting things. Dumbfire weapons are very vast with a small hitbox, or slow with a large hitbox. A good slide or boost can get players out of the way of tracking weapons. The "attack the leader" weapon doesn't autotarget the leader and blow them up, it puts obstacles in front of them that last long enough to affect the top three at least, meaning it levels the field, but doesn't deliver a win for the second place player. There is crazy shit happening in every level. Most of the tracks get tore the fuck up and change during the race, sometimes all 3 laps are different, and there's cool thematically relevant stuff going on most of the time that affects the race. Giant air battles, rampaging zombies, and a rapidly flooding opera house thing in New Zealand god damn. tl;dr - fuck Mario Kart, Sonic and All-Stars Racing Transformed just wrecked Nintendo's shit. MK better step it the fuck up, because this is a fresh take on the kart racer that makes big changes to the formula that were desperately needed.
