First post here after reading the forums for quite a while...
I'm 26, and have been working on my game for the past 5 and a bit years; 3 of which were mostly spent learning. I've just launched the website and the first gameplay video of the game and would love to get your feedback on both.
The game/simulation is built with Unity and I've written the physics system from scratch to simulate the kart. All written in C# and uses raw RakNet for the multiplayer. FPS controls are also implemented in the game so players can walk around the pits in between races. I've also added a leveling system that allows the players to earn points for winning/fastest laps etc, which they can use to unlock additional content to customize their avatar/pits.
I know its a racing game and a bit different to what you guys generally get asked to provide feedback on, but it would be great getting views from non racing game players. The video only shows the driving part of the game at the moment, so I'll try and get another video of the FPS mode later.

Looking forward to hearing what you guys think! Don't be too harsh
