KartRider Rush+ might be good, actually?
It's hard to find good racing games on mobile. Most of them are free-to-play, and free-to-play racers generally suck. Even Nintendo couldn't put together a competent Mario Kart game, opting instead for a weird score chaser that resembles--but feels nothing like--actual Mario Kart.
So, when Nexon released KartRider Rush+ earlier this week, I had low expectations, but I decided to boot it up and try it out anyway. I played a few races, and then I played some more. Then I joined a racing club, found myself friending people, and racing even more. Before I knew it, my week was consumed with playing KartRider Rush+ because--somehow--it has managed to create a free-to-play racing experience that actually feels good.
