GRIP is a fun arcade racer, though it is not without its issues.
This game was made by a developer (Caged Element) that had fond memories of Rollcage, and wanted to make a game like it, similarly to how Horizon Chase Turbo is made in the vein of the old Top Gear games on the SNES. They did, by and large, a pretty good job.
The visuals are not too bad for a downport from more powerful hardware, but unfortunately there are a few tracks/arenas that do still have framerate issues as of the current version (1.0.8.) The Switch version also only supports 2-player split-screen instead of the 4-player available on other systems.
The track design is somewhat of a mixed bag. Generally speaking, the more open/wide tracks are more enjoyable than the more technical/narrower tracks. In the latter, the weapons are more difficult to use. More annoyingly, some of the track design tends to lead to some jankiness where your vehicle will unexpectedly end up bouncing violently after a landing or becoming attracted gravitationally to the wrong part of the track, more than likely costing you enough time to ruin a chance at a good finish on the harder difficulty settings. You can restart races, thankfully, but losing due to jank is definitely frustrating!
There's also arenas that are straight-up car battles (ala something akin to Twisted Metal, Mario Kart 8 Deluxe's battle mode, etc.), which can be fun although the AI doesn't tend to be very competent (though, the same could also be said about MK8 Deluxe.)
The controls work fine, I personally didn't have any issues with them. The physics are generally OK, too, though as mentioned above, the occasional bit of jank likes to rear its head every so often.
GRIP has a flavor all its own, and I don't regret picking it up. In general I liked it, though I waffled as to what rating to give it. I ended up rating it at 4 stars, but honestly if I could I would have given it 3 1/2 stars. It's fun game with some annoying flaws that hold it back from true greatness. I would recommend this to those that can put up with this game's quirks.
