I have done a series of surveys about circuits, oriented to the interest of adding new circuits in a future implementation. I don't know how relevant this information might be but I found it interesting to do these surveys in my league. If you need some translation tell me, although I don't think it is necessary beyond titles.
Most boring circuit of current iGP?
Which circuit would you prefer to disappear from iGP?
Which F1 2017 calendar circuit would you rather see in iGP soon?
Other circuit that you would prefer to see in iGP?
Another circuit that you would prefer to see in iGP?
