Unfortunately this used to be a good game (~6 years ago), but the developer is now bored with this game (16 years had enough) and has started to work on another project. The active managers are dropping from a high ~12000 to ~6000 and they are sill dropping due to the incomprehensible rules, toxic community, dead forum, no updates (last big update was ~2016), and only concentrates on selling you meaningless avatars/images like your own car livery for 50€, or your own personalized helmet for 20€. The worst thing perhaps is that they allow ~9 year olds to play, despite the rules stating players must be 16 years or older to play, this game is far to complicated for most adults to understand let alone a 9 year old. Now a game should be fun, but this is a boring game that does not even reward you when you do everything right! Examples your first race that you spent hours preparing for and you crash at the start and are out of the race. Race 2 you try again and this time you have a puncture 2 laps from the end when you are in 1st place and again out of the race! Next race your engine blows up and you are out of the race, and this crap continues race after race and no one will tell you what you are doing wrong and just say that they are randoms and get over it, or read the rules.WTF!
TL;DR
Dying game, dead forum, toxic community, incomprehensible rules, no help, numerous bots (fake accounts) to bolster the game numbers, you need to be an expert in spreadsheets, not a racing game but a boring numbers management game that rewards you with randoms that ruin your races, no mobile app and a developer who has lost his passion for the game a few years ago and this unfortunately now shows in the decline of players season upon season 🙁
