this game had a long and painful (and confusing) development for 5 years, starting in 2013 . And since 2018 is the last release, we can actually talk about 3-year-old game now, which graphics was obsolete already in 2016, not to mention in 2018 or 2021. What was "abandoned" by Kunos and thrown for modders sake, thanks to full debug possibility, started to give visible outcome, in term of enhanced game functionality and up-to date graphics postprocessing features.
It is a toy that KUNOS, bored with it, left for us, and we made it even more enjoyable than they could have ever imagined
