For those who haven't heard of Threes, I highly recommend giving it a try. It's the original game that 1024, 2048 etc were cloned from (and I think it's still the best by far). Wikipedia has a good summary: https://en.wikipedia.org/wiki/Threes#Legacy
This argument has always been silly.
Three's didn't invent sliding tile games. Sliding tile games existed going back to the 1980s and 2048's mechanics are different enough that I don't even think they're comparable.
They've existed in wood for a lot longer than that.
