Personally, my favorite Mario Kart is Mario Kart 8 Deluxe. Even though it's a port, there are a lot of wonderful new features! It's my 2nd favorite game to play with friends (the 1st one being Smash) When the Switch launched, I played Mario Kart 8 Deluxe all the time when I'm on the bus, (the ones with little tables behind the seat, I don't feel comfortable without them) on the plane, or sometimes at work. Although I don't play it as much alone, the improved battle mode and added characters made playing with friends fun! My personal build is Inkling Girl + Splatt Buggy + Sponge Wheels + Standard Glider. My favorite mode HAS to be Renegade Roundup. It's just Cops and Robbers, but Mario Kart. That feeling you get when you free all your teammates from the cages feel SO GOOD. My least favorite, however, is Coin Rush, I just can't seem to get enough coins! I still remember that time when I made all my friend's coins fall out, and this CPU Baby Mario took ALL of it. He just stole em all. The anti gravity sections are also pretty neat too, I feel good when the karts bump each other and they do a little spin boost. It's also great when you do the pose when leaving a ramp or bouncing on a platform. For the Grand Prix, my favorite is 100CC, 50CC is the slowest, 150 is fast, and 200CC is TOO fast, but 100CC is just right. Or maybe I should get gud. The moving also feels great, drifting is smooth and throwing items are quick. Compared to other Mario Karts, the movement in Mario Kart 8 Deluxe is the best. I do wish they'd bring back some karts from DS tho. I was also surprised to find out about the Mercedes-Benz karts, those were neat. I haven't touched online play yet, as I don't have sudden urges to play Mario Kart when I wake up or during work. My 2nd favorite would probably be Mario Kart DS or Mario Kart 7, as I also played those two all the time in long travels like bus train or plane, as well as during work (shhhhhhh). Not as much with friends though, as most of them don't even own a 3DS
. Movement was also smooth on those two games, I thought R. O. B. was a really cool addition. Was never a fan of the balloon popping in battle mode though. I also have Mario Kart 64, but I haven't played it enough to actually form an opinion about it. My least favorite ones, however, are the arcade ones. I played them at my local mall. It always felt weird to me. To my cousin, no, but for me it just feels off. The PAC-MAN characters were a neat touch though.
