So as some of you may already know, MOT is my first MP experience...I've spent decades now building in singleplayer career mode and making my own scenarios too. Here is one project I've been working on, from the 'Make Your Own - Six Flags' where the goals have been changed into a sandbox.
No cheats or trainers, just the vanilla game plus DLC! Bear in mind its still a WIP so many scenery items including greenery are yet to be placed!
If I can figure out how to, I will include the game file too if you wish to have a closer look!
