N64 era, when Nintendo moved to 3d...not necessarily the BEST era, but when they made Mario 64, Oot/majora, waverace, star fox 64 they blew my mind and were at their most innovative...to me at least. With the GC they were merely extending from this while trying to make a console that was more like the competition ( Nintendo always do better both financially and creatively when they do their own thing) and we all know how that worked out ( I preferred the GC to the wii though, cos at least Nintendo were still concentrating on making core games at that time!!! Also the era that gave birth to PIKMIN, the best new Nintendo ip since the good ole days!!!)
Some may argue they were more innovative when making games like brain training, wii fit, wii sports etc as they reached mass appeal with a whole new audience, and created new ways to interact with games yadda yadda but I'm into more traditional video game experiences and largely ignored this period despite owning a wii and several models of the ds
