I enjoyed a few of them. GtaV, or Borderlands 3 (altough part 2 will be my favorite part forever)
Civ6 was merely only a demo version, and TW:Troy really sucked and helped me save some bucks.
But mostly I just add them in the hope that Tencent will pay a few cents to The developers who created those games in the first place.
But I won't buy anything there. Games that are only sold via this platform don't exist.
