I've played a good chunk of racing games on the Switch at this point, and Speedway Racing is by far the lowest effort I've seen yet. If it functioned properly and ran smoother, then it would at least be worthy of consideration as a compact title. But in this state, you're better off avoiding it and picking just about any other racer. Sega Ages: Virtua Racing isn't stock car racing like this, but it does have similar arcade-style circuit tracks. It's about the closest thing, and despite being one of the earliest 3D racing games ever, it's a far more enjoyable experience than this poor indie.
Rush Rally 3 is impressive for being the product of a one-man band. It has a sizeable amount of content and accessible driving model. Its simplistic presentation is a bit of a bummer, but this is still one of the most balanced racers on Switch so far.
If you're accustomed to the deliberately mundane nature of simulators, then Fishing: Barents Sea Complete Edition should be a familiar outing. It's not as hands-on as the typical fishing game, which makes it feel more automated and lifeless. Still, it does a relatively decent job at simulating the life of an industrial fisherman. It's rough around the edges, especially here on Switch, but it's by no means a bad game.
