By far my favourite MK experience. Also the game I refer to when people have that theory that your first MK is always your favourite, since I started with MK64.
I feel like in discussions about other Mario Kart games, everything is more about the track list, modes, etc as it should be, but when it's MKDS it's suddenly all about how snaking ruined the online and how it's not a skill, like it ruins this silly franchises competitive viability. I played online briefly and then enjoyed it and left it. I did some snaking and it wasn't really for me, and that never mattered in my group of local /online friends. If anything it made it fun to watch the speedrunner for it last year.
The actual package is fantastic. The new tracks contained a lot of the best in the series, finally taking more inspiration from other Mario titles to make stuff like the airship foretress track, delfino plaza, Luigi's Mansion, etc. Loved all the new karts, and loved finding out you can unlock ROB. Mission mode was even fun and quirky with boss battles, and it was all handheld. Perfect to play after school or whatever when a lot of my friends lived a bit too far away for me to visit them.
