Im in the “WoW 2 would likely be a rather mediocre game, if it were ever to become a thing”.
Why? Development costs. Blizzard has been trying to cut costs everywhere for the past few years. There is absolutely no way a sequel would get the funding it would need to be made.
Not to mention it’s a gigantic risk with little reward (for Blizzard). At best the could capture an entirely new audience while old WoW players stay with the old game. And at worst it would just pull away some current WoW players while failing to capture a new audience.
And unless they hire an entire new team of people, they would have to pull away staff from their current game to work on WoW 2. Which realistically would take the better part of a decade to make. And as a result would likely be infested with microtransaction and pay-to-win mechanics. Praying on whales would be their only hope of recouping the development costs. Especially if you factor in the opportunity cost of losing development time on other games.
Maybe im just jaded or pessimistic. But i can’t see Blizzard making a sequel to WoW while the current one is still going. Or investing the resources needed for such a project. Or making a game that will live up to peoples expectations. Just see this forum to get an idea of what people want out of a sequel. It basically boils down to “The bestest game ever!!” and/or “You can do EVERYTHING!”. And if those expecations are not met, it’s going to bomb right out of the gate unless the game can capture an entirely new audience.
