My reply: "Your a fucking idiot."
Ha ha ha ......let me jump on the wagon, and although I think somebody mentioned it already, the answer is NO ! ( Keep going Ha ha ha ....)
But really, it reminds me of a long time ago when I was in Germany and those were the times when the PSX was brand new and its main competitor Sega Saturn was still considered a contender.
I went to a local game shop and while I was looking at some games, there was this middle aged guy with a mustache who approached me and told me to be careful.....cause PSX games wouldn't run on the Saturn or that other CD-rom based console they had at the time ( like I didn't know ) and his explanation was that companies, in order to make more money made the CD-ROM drive spin the other way around so that you couldn't play one games on another......:LOL
I said Geez, thanks, I 'll surely be careful......
So you see, it's in the human nature to get confused when new hardware comes out, and if all you need is a simplified explanation on why certain games only work on some system, I'll simply tell to the TO that being Nintendo such a greedy company, they made the shape of the 3DS cartridge slightly different so that it wouldn't fit into the DS/Lite/DSi/XL to force people to buy yet another console !
