Really sad to hear, hard to make any sense out of their decision. The judicial system can be senseless sometimes...
This is disappointing to say the least...
Are there any details you can disclose? How were you contacted, via e-mail, letter, phone, ...? By a lawyer? Is email legally recognised in your country? What do you mean with "they don't want any money", did you try to make a licensing deal? You cite 5k Euro? What if you just call it something different and replace branding with fictional ones (and obviously use exclusively scratch made stuff)? I'm not a lawyer but I really doubt circuit owners have legal leverage on anything but their brand (which is what they license out, so it's about trademark, not copyright law I believe), especially over a non-commercial entity like a mod.
That’s just one thing which won’t get into my mind: why be against the virtual recreation of their own circuit, it’s good marketing for their track (unless it is a bad recreation of course). There are too many lawyers on this planet concentrating on the wrong or unimportant things, that’s for sure.
Oh I forgot to say, sorry. They do NOT give license to individuals, but only to companies (like Assetto Corsa). They stated that clearly. But they didn`t say anything why is that so.Ok so it's simple then, you wanted to make money with the track, pay the license. It costs 5000€, period.
Now that we got the full story, it's completely understandable why the owner decided to do that. Don't take this as an offense, but it was your bad move, so it's you, not them to blame.
Terrible shame, but I can understand both points of view - its their property, its up to them to decide whether or not you can publish under their name. And I would have imagined it to be much more than 5000€ tbh.
But I'm not sure what the rules are regarding the name change that many suggest. How can they police it? Where is the line drawn between a passing resemblance and a too similar of a likeness?
In my mind its sort of like banning someone from making a clay model and posting photos of it online etc, just because it looks like their track/car/whatever. Is a 3D model any different? If you don't refer to the name or anything like that, is there really anything they can do?
I'm sure I've seen games in the past which feature 'chinese copies' of cars/tracks, different names but obvious what they are imitating.
Anyway, net time you'll know that if you want to get in contact and strike a deal, do so before spending all that time an energy on it. If they don't like, its not such a big deal.
Otherwise not making any contact may have been the better option.
They do not want their brand associated with an inferior* product. Coca cola are not going to let you use their name for your homemade cola either.
The minute any money changes hands for a product, a contract is invoked. If it is given free, no contract and you not making money off their brand.
*I am not saying your product is inferior, but when a studio such as Kunos release it, there is a certain quality assumed.
YOU DO NOT NEED TO BE MAKING MONEY TO BE VIOLATING THEIR IP RIGHTS.
Just have a look at Sakito on PCars.
In the WMD-phase of the game it was the Suzuka track layout, but apparently SMS couldn't make a deal with Suzuka license holders.
In the released version of PCars Sakito is significantly different to Suzuka.
So I guess an identical layout even with fictional name and no real sponsor textures wouldn't be allowed.
