Eh, even with track creation, I prefer Modnation Racers and its spiritual successor LittleBigPlanet Karting. Shame both games are stuck on the PS3, but then SuperTuxKart still looks like it came out of the PS2. They run well in RPCS3 and online still works for track sharing through fan servers.

Also, I wasn't that impressed by Crash Team Racing Nitro Fueled. It does have tons of content, certainly worth the price. Never played the originals and the remake sure does look pretty, but the track design feels pretty simple, probably because they're from a PS1 game. Simple track layouts, few gimmicks. Some people might prefer that, but not me. I'm sure CTR beat the socks off Mario Kart 64 back in the day, but the tracks in modern Mario Kart are to me far more interesting. I expected more out of it given all the hype. Plus, for some unfathomable reason despite being multiplatform the game was only released on consoles, not PC, so that's another game you have to emulate to play on PC. And if you do have a console to play it on, it's locked at 30fps regardless of platform, which is disappointing for a racing game. There's a 60fps mod if you emulate tho, thankfully.

All-Stars Racing Transformed does have my glowing recommendation, though.
