1. BeamNG has become one of, if not the most advanced driving simulator there has ever been. It's realistic, has some mind-blowing physics and also amazing graphics. All of these features help the player be immersed and feel like he is in an actual vehicle. 2. There is one problem however: the particle system is very outdated and since one of the primary visual components to a game are the particles, i feel like they require an overhaul. There is also another problem: the quality of the particles is not consistent between its various types. Some of them are of decent quality while others are purely atrocious (the most notebly being the flames). Speaking of particles, another addition that i think would be awesome is the rain particle system. There is already the texture and the physics of wet road coded into the game, so while it is raining all the roads would just get coated with it. 3. I know that this last one is not necessary a particle related suggestion, but i think paint scratches could complete the demolition aspect of this game. I've written this not to critique the game, but to give my honest opinion and feedback about it hoping to help improve it. I really hope that the BeamNG team reads this. I wish you all the best!
