I even don't know where to begin, so let's talk about emotions given by this game. Being pretty cheap, that game give you a tornado of emotions. From being extremely happy because of your first place, to being angry as Ares (god from greek mythology) when you run over a cake which is lying on the road. Mix this cocktail of emotions with friends (more is better) and you will get unforgettable experience and memory for years and years, but this is only the beginning. The game's max graphic will amaze everyone who has a monster of a PC, and low graphics will allow users with potato computer to relish its great mechanics and gameplay without any lags or fps drops (Thanks to skilled developers).

Main game's part is racing and in this game it's perfect. The last parts of "Need for Speed" and "Forza Horizon" are just cheap copies of this masterpiece. Driving in this game is exceptional. Despite that learn them is easy, to master your driving skills you have to waste years in this game to achieve at least some result and not being a noob.

Maps in this game are so well-made, that I even don't have a word's to describe them. Every single corner is thought to trifles out and there are no unnecessary details. The amount of maps is big enough to give you a thousand hour of pleasure, and don't get bored.

Amount of characters, cars and customization will allow you to express your inner world and by the same time will make you look stylish. Don't forget, that this game is made leaning on Garfield's universe, so if you want to dive in to your favorite racer and learn his lore and character you can read wholesome Garfield's comics (But this is topic for another talk).

And finally - music and sound effects. Music in this game will load you in to this wonderful world and will give you right mood. Amadeus Mozart, if he was alive, would learn some things from composers of this game.
Sound effects are making the feeling, like you are actually sitting in kart and riding for the greatest cup. Sometimes it's hard to understand, are you even playing, because everything feels so realistic.

My over all opinion: Games like this are an incredible rarity nowadays, and I am surprised by its low popularity. There is nothing special, just people can't understand highness of this game, they are playing their AAA games, and can't see the beauty of such simple, and at the same time gorgeous game, but this is their problem, I am happy to be part of this community, and wish for more people to discover this masterpiece.
