mmm there is and not. Theme Park was also WIN native as well. Its like game with few DLCs/Addons. Maybe still not enough to split into separate article. But they are officially considered as separate title. Both on consoles they got differ titile and ID, and on PC as you saw it on sourcelink by Theclaw135 it is get alternate name and marketed as differ game.
For example Need for Speed 1-4 got some downloadable content from website, but each region initially got one per region Free-LC bundled on disc. And Japan region got at same time as usual own Retail+Free-LC of Japan brand car, and entirely new titled NFS 1-2(-? some else too?) with all cars replaced to Japan only brands.
Shin did not replace every "cars" (levels), but add few new. As exclusive DLC/Edition. The only reason to split is their official publishing marketing.
Although if technical info are same maybe enough to state article do cover two games, while series template deffinetly should list it as two differ titles. As it is happen on some PCGW articles. I think there is no issues in listing game separately for anyone. While split article is debatable. Right?
