The sixteenth Kirby game ever released and the ninth spin-off, this time HAL Laboratory experimented with the racing genre and created Kirby Air Ride.

Despite being a spin-off, it was heavily marketed, with two specials in the anime Kirby: Right Back At Ya, TV commercials and even printed ads... Which sadly didn't help that much, as the game sold less than one million copies and received mixed reviews.

However, nowadays it has a cult following and it influenced other Nintendo games, especially the Super Smash Bros. series, developed by the same studio, and Smash Bros. Melee was created using the same engine, which is fairly obvious when you notice how similar the style and menus are.

And it's understandable that HAL Laboratory and Kirby fans still appreciate Kirby Air Ride, as it is a really original and interesting racing game with three modes, each one with 120 achievements to unlock, meaning that you can do 360 different challenges and get new vehicles, stages and characters in the process. Also, if you get 100 achievements in one mode, you unlock a bonus cutscene which serves as an ending , so, in order to "complete" the game, you need at least 300 achievements, something that takes way more time than your average Kirby adventure.
Of course, you don't have to do that in order to have fun, but it's a really nice alternative if you get bored from racing against other NPCs and players without a real objective, just like the challenges from the Super Smash Bros. series.

The first mode is Air Ride, which is the standard racing mode. You can customize the amount of laps or play in timed mode, as well as try to set records in the Free Run mode. It's the perfect place to start and accustom to the gameplay, which is fairly simple, as it only uses one button and the joystick, but every vehicle is unique and their controls are vastly different, so it's important to prove them and decide which one do you prefer or is better suited for the stage, as some of them are very useful in the air but slow in the ground, while others are really fast, but have a hard time with curves, and so on.

The second mode is Top Ride, where there are only two vehicles available to use and the courses are much shorter, but instead of trying to drive better than your opponents you have to use the random items that sometimes spawn (although you can turn them off if you want to test your skills) to win. It's pretty chaotic and fun, and because the gameplay is totally different, it is a nice change of pace if you get tired from the other modes.

And the last mode is City Trial, perhaps the most popular one. It is divided in two sections: City trial, where you explore within a time limit a huge open world that is full with power-ups, random events, different zones with secrets and vehicles that you can change whenever you want, and the Stadium, where you use your powered vehicle to compite and prove you're better than your opponents in a random event, like a Destruction Derby where you have to defeat them as many times as you can, or a flying test where you have to glide farther than them.
Of course, the real fun is in the city, where the experience and strategy is never the same. Maybe in a round you will be attacked by Dynablade, or a UFO will invade the city, or all the vehicles will run amok, and these are just three examples from the many events that can happen. This is also the only mode with the Dragoon, the legendary vehicle that appears in Super Smash Bros. as an item, so you have to play for hours if you want to experience everything the mode has to offer.

In conclusion, why was the game poorly received when it came out? Probably because if you don't know that you have to unlock most of the vehicles in Air Ride and how expansive City Trial really is, the game will feel pretty barebones and basic, especially if you compare it to other racing games like Mario Kart: Double Dash or F-Zero GX.
Which is a shame, as Kirby Air Ride offers a really original experience that no other racing videogame has and it deserves more than be known as an obscure Kirby spin-off for the Gamecube. Hopefully someday it will be released on newer platforms so more people can enjoy it.
