I found this, a new simulator (all about motorsports in Argentina) that looks very similar to the Madness Engine that AMS2 uses.
This was announced yesterday as a team up between Bundle Games (aka the biggest a-holes in the history of Argentine simracing) and REG Simulations. As an Argentine, I think nothing good will come out of it; I would not have this title on my library even if it was gifted to me, and I won't be sad one bit if it turns out to be a flop or never comes out. Because, together with more reasons and stories than what I could write here, it's for this very group of people that Reiza could not have more Argentine content in AMS2. They can Foxtrot Oscar for all that I care. Edit: I mixed up two different modding teams and said something about REG Simulations that it's not true. The rest still stands.
Do you have any link, post, website? Or maybe you could share this story with us. I'm really curious now. I was very hyped about this project until I read your message.
