If there would be an extra package for the Nürburgring, GP-Track, Nordschleife, GP - Track and Nordschleife combined (which is driven in VLN Series and is used for the 24hr race) and that kind of stuff I would pay whatever that package is about to cost, because secretly this is the best sim ever. It just needs more improvements. I am quite sure that developers from other sims and I won´t mention them here have stolen your hole concept when you startet your project. It´s time to hit back!
