I dunno, I feel like most video games have gone stale from my perspective. In fact there isn’t one which truly has much value to me, which begs the question whether the games are the issue or whether I’ve just grown out of them in general. Wouldn’t blame blizzard at all.
Personally I like simple games. Something you can hop onto and pretty much get the gist after 10 mins of play. Multi-player half-life 1 comes to mind for example. Having crazy in game menus and character progressions or skins and yada yada ya are just fluff I no longer care for or have time to bother learning
