One critical component for a multiplayer game to have longevity is LAN multiplayer capabilities. This game is supposed to have it but it does not work. All players connect to the game lobby but as soon as the game is launched everyone is disconnected with an error. GOG support was useless and I'm guessing the developers aren't going to be fixing it. I posted a bug report on their official bug reporting website, but it has not yet been acknowledged. Because of this critical component not functioning properly I'm only giving it 3 stars because single player is a repetitive grind and is not all that fun. And without LAN multiplayer working properly its life will be much shorter than it should be. I hope the developers will fix the LAN issue but I'm not going to hold my breath.
I had the CD version of this game years ago. Saw it on GOG and grabbed it again. Just as fun now as it was then. That said, when I upgraded my computer to Windows 10 (they list Windows 10 as a compatible OS) the game now crashes when launching a race. I have tried it on two other Windows 10 computers just to confirm and they all crash. I have a support ticket with GOG but honestly don't expect it to be resolved. If they do resolve the issue I'll update this review.
