To date, Resident Evil 2 Remake is the best-selling RE ever, as well as being considered one of the best exponents of the historic Capcom brand.  Initially arriving on PC, PS4 and Xbox One and then also landing on PS5, Xbox Series X/S and Nintendo Switch, it seems that Netease Games, a studio dedicated to mobile titles, is also planning a version for mobile systems.  From the LinkedIn profile of Yeo Yee Yang, game designer at NetEase, a mobile version of Resident Evil 2 Remake described as "under development" is in fact mentioned.

Resident Evil 4 is a game I’d recommend to absolutely anyone. It’s a masterpiece of the survival horror genre, with smooth, satisfying combat and some fantastically spooky set pieces. The original was already a stone-cold classic, but the 2023 remake refined its graphics and gameplay mechanics, making the game feel better than ever. It’s something that everyone should play at least once, but if you have literally any other options, you probably shouldn’t play it on mobile.
