I have been playing TEAM SONIC RACING on the XB1X and it's good but not great.
For starters it doesn't run at a steady 60FPS, which for the most powerful games console in the world, running a bloody kart racing game, is crap. I'd rather they'd dropped the resolution to 1080p to lock in 60FPS, rather than run at a higher res and drop frames at the worst possible times. (Or at least leave the option of 1080p/60FPS on the table.)
Moreover, the way it drops frames is awful, with some weird sort of double buffer that means you get a proper lurch when it happens, that can totally fuck up a drift swap through some tight corners and lose you a gold. (The ring challenge stages in particular are really harsh and a single mistake will cost a gold.) It's not just me being picky, if you watch the Digital Foundry video on the PS4 Pro version which drops frames in the same way, they say it genuinely takes you out of the moment and negatively impacts the feel of the game - and it really does.
Mario Kart 8 - this is not.
Beyond that it's a very competent game but not jaw dropping, it terms of pure fun I think Sonic All Stars Racing Transformed was better, and it had a wider roster of Sega characters.
The drifting feels a bit off too, I can't quite get locked into the zone with it, honestly, OutRun2 Coast2Coast felt better on the original XBox five million years ago.
The story and cutscenes are object lessons in banality, do yourselves a favour and skip them.
The music ranges from great to annoying, seemingly at random.
Oh yes and instead of nice distinct icons like you get for powerups in say, a Mario Kart game, here you collect 'wisps' which all sort of look a bit the same so you really have to learn them.
Despite all that, I'm having fun with it, and at its best it's a beautiful, fast, exciting, challenging kart racer. I'll probably work my way through the single player campaign a few stages at a time. It's an enjoyable game, don't get me wrong, but it has its flaws.
I'm feeling 7/10 territory at the moment.
