I gotta go with the N64 since I have great memories of playing that console. I didn't grow up with the SNES so I don't have any childhood memories of the console, and there are some great games that were released for the n64 that weren't even Nintendo related such as the Turok series.
Nintendo and Super Nintendo were my favorites. Granted with each release of a new console I had one. But I love Nintendo because of some of their first games, example Duck Hunt. I LOVED/LOVE that game.
I dont own any Nintendo consoles at the minute but my favorite is the Super Nintendo Entertainment System.Reason i love playing beat em ups and this games console got me into them and i have been playing them types of games for years now
Probably either the 3DS or Nintendo 64. Loved them both to death. : 3
I think Nintendo 64 because it's what really got me into gaming, and 3DS because it (along with DS) has such an amazing library of quirky and interesting titles.
