Ah, I see. Well, my intention was to simply add evidence to the claim that the creator of the well known 2048 didn't know about Threes when he created it. There seemed to be a dispute, so I remembered the comment and linked to it.
The webpage for that 2048 references Threes, so even he is supporting a line of direct influence.
the point is that you cannot download an iOS app without encountering its description, so to say that you know about 1024 and not Threes is deeply suspect.
Do you read iOS descriptions of apps you know you're going to download? I sure don't! If I see a friend playing a game that looks good, I download it without reading.
