do you mean that competitors would do better than Trackmania. How silly of youThere's not really any competition between developers and that's why the progress is very slow and not much has happened.

anyway, I am in a good mood, so I will not say that your main argument is that the game is not good enough is still really negative. Is the gameplay, the graphic, the fact that we had relay servers since years, the ability powerfully to create maps, the dedicated servers, the lan mode, the replay making tool or else that other developer would do so well? look around, and tell me how many games, apart from SM have that.
I tell you, not enough people look eSport for eSport, and not enough pratice racing in club, because it is a "solo competitive" format. So, you need to wait for eSport to be bigger in order to have this type of discpline really popular, or increase in production quality by commentators, circuits, make the use of nationalities or cities to bring interest of spectators etc. Your things about skidmarks or the passion of the developpers are gimmicks. We are more passionate about really bringing eSport than many other devs, we made a racing game in 2006 for this, after having made a competitive one before, we have kept the gameplay solid since years etc.
