I think that it is a reasonable claim to say that Minecraft deserves popularity. Heck, I think Minecraft is pretty cool, but I will never play it. On the reverse side tho, I think that it is also reasonable to claim that Fortnite deserves some popularity as well. Both Minecraft and Fortnite are able to be popular without disrupting the other games player base. I think that Minecraft was still very popular even when Fortnite was released two years ago, so I don't think that Fortnite needs to die so that Minecraft can be popular again, because it already was popular.
