That's the problem, they don't care but it's going to screw them up in the end. When people eventually get sick of all their 'retro' ********, or their original audience has grown up past Nintendo, they're going to realise they haven't made anything new in years. They became too insular and acted like they didn't need to compete with the rest of the industry, just making their own thing. I think they've totally lost their way.
Think back to the N64 days. Some of my fondest gaming memories WEREN'T from Mario, Zelda, but from games like Goldeneye, Perfect Dark, Jet Force Gemini, Banjo Kazooie, Conkers Bad Fur Day... It seems to me that when Nintendo lost Rare, they lost a huge creative drive for new IP's. What was the last great, successful, original first party Nintendo game. Pikmin?
