The thing why Der_Bayer and/or me havent made a fourth Season is the amount of the work needed for.
I do know that they are a bit of different to what we have in MP and Scenarios, as you just know WHAT to do, but HOW you solve it is your beer. Everyone has his unique style of engines as we have seen already, you really train for a real campaign

Its about creativity, knowledge and a bit of marketing - which makes it way different to the Multiplayer.
It somehow ended up in a popularity contest, which is kind of shit for other players which are new, but really really good and deserve the votes.
BUT! The work amount is really high. All those additional stats like Acceleration, Top-Speed, Economy or Ratings are made just for that specific theme. Sure you can copy and change them, but they always need calibration and comparison data from real cars. I'll be honest: Creating a Round took me about 3-4hours. Thinking and choosing a theme, thinking about additional stats, finding data, making/calculating/calibrating those stats and then a small testrun.
Then after a around 1.5hours to count votes, collect data, make the placement and then presenting it. It IS fun, but for 10 people its a bit of too much work.
I know that people want it to continue, and I CAN continue it, no thing. But I would need ideas for new themes - alot of them.
Thats what I can tell you from the host side of the TEC.
