Hi there.
Sometime ago on my track forum I posted this message. Hope this help on this particular question of new trackmakers, as me and Edu_13 for example
About trackmaking: The more I learn, the more I like it. But think also we got a responsability on this trackmaking stuff: Our new tracks MUST appear as real as possible. Someone says about Shuttle Shangai´s that his work was like a hidden track that we never found out in the game - I tottally agreed! It is really a professional work, a very very dedicated work, and we should try to do the same always, and even better with all the improvements from 3deditors (better and better each day) and tutorials (Lo2k, Maverick, You, Tom, James, realgpx stuff, these foruns here at grandprixgames.org) and everyone passionated about GP4.
This is the best F1 simulator and our job must keep it in the high levels. Hope we achieve that.
Another thing that must be respect is about permissions. This is of a very big importance and demands a very tiny gesture. Just a post or a readme-mention would be help - I prefer a personal mail. GP4 is more about formula one, more about real-life simulation than just a game... We should keep it. And be responsible for that as well...
Anyway... Cheers you all, trackmakers and formula one fans.
