I didnt say it would.
He said, "anyone that thinks that the 3DS sold 70+ millions "in spite" of its 3D has no idea what he's talking about."
To me that implies that 3D was a major selling point of 3DS and sales would have been much lower without it hence why i asked him that question.
Maybe it actually implies that while 3D clearly wasn't a major selling point for the 3DS, it wasn't actively driving customers away either. Considering that unlike the Wii and U's primary controllers and selling points, it was entirely optional from the get-go. The only manner in which 3D hindered the 3DS' trajectory was the initially high price point at launch, but I have yet to see anyone acknowledge that this had just as much if not more to do with the lack of first party software available as well. The 3DS launched with such memorable titles as Steel Diver and didn't really begin to take off until games like Ocarina of Time 3D and Mario Kart 7 finally launched. Someone correct me if I'm wrong, but I recall those games coming after the price cut.
