It features a beautiful and very atmospheric retro pixel artstyle encompanied by beautiful and haunting tunes with as much of a melancholic as well as an deeply philosophical atmosphere and topic to it. It's also nice gameplaywise since it's one of the rare Point & Click Adventures where there are different ways to solve a puzzle in many situations, what makes it engaging even on a second playthrough. Also your actions in the game may lead to different outcomes in the ending.
I loved the first Moto Racer on the PlayStation as was quite surprised to find out that the PC version features a level that the PS1 version doesn't have, the snow level. Moto Racer 2 on PC was my first time ever playing the second entry in the series and it seems to improve massively on the first installment. Very fun. Moto Racer 3 though....wow.....as if they planned to turn the series into something completely else, a horrible menu UI design, extremely unresponsive controls and nothing is there that made the first two games so fun. A totally bland and generic thing that doesn't even resemble the franchise in the slightest.
