Comparing an MMORPG to a Battle Royale game..... And PUBG doesn't have much hype at all. It just got popular through word of mouth and streaming. As well as it's basic gameplay of being able to pop in and out at will.
PUBG and WoW have one thing in common. Accessibility. Both games are easily accessible today, not complex and allow you to play on your own time.
And you are being completely dishonest saying that there is no hype for new expansions. But well considering your stance on the matter that's not exactly surprising.
