I'm pretty sure they will give Tencent's games a way to comply by changing some petty stuff and keep the others banned.

As someone else mentioned, Fortnite is tencents game, they’re a 40% stakeholder in epic and this is a huge upset for them. So maybe this is like you said temporary.

Including the mobile version of PUBG (it was created completely in-house by Tencent).

There's actually multiple branches of PUBGMobile, a Chinese version (called TIMI) and the rest of the world (Lightspeed/Quantum.) Both were begun and developed in parallel, are pretty close in gameplay and mechanics but each has their nuances. The TIMI version notably has most of the premium clothing and items for free since lootbox systems are considered gambling in China. Also, green blood.
