Not sure what point is.

I didn't say anything about "real" gamers leaving Nintendo's boat to join Sony and Microsoft, and if they did that ( which probably a lot of them did) they did it in earlier gens and not this gen.  However, a number of them did stick around during the N64 years and Gamecube years if forum posts are anything to go by, and they're the ones that seem to praise games like Wii Sports and Wii Fit for being some of the best games ever due to their company loyalty and to insist that things like metacritic scores of those games must be wrong because according to them those games are all better than the likes of Uncharted.  However, from my experience, I hardly ever hear them criticize Nintendo for not doing things like innovating by releasing new core ips.

Now a lot of us thought that if Nintendo really did take off in popularity again what they would do is just drop all this casual fluffbunny stuff and begin to concentrate exclusively on bringing out the best core experiences again;  however, that's very much not what they've done.  And, if I was to praise one thing about Nintendo fans it would be the Operation Rainfall campaign; however, it took only the greatest effort to get Nintendo to release those three titles.

What are the things Nintendo fans wanted earlier but didn't get until the Wii?

Yeah because their fans wanted core experiences like Metal Gear, Final Fantasy, and Halo.  And now that they've come back they're just praising Nintendo for the few scraps Nintendo gives them like more Marios, and not giving them any flak for giving as much time to Wii Fit U  as to Mario at their recent E3 Press Conference rather than demanding that Nintendo shows off a new core experience as formidable as those in the best new core experiences that were hyped for the other consoles.

Gotta admit I mixed your posts with someone else's .. ;) sorry

But still: why do you think the fans are still the same as the ones before and just defending due to their love? It's actually a lot of younger or newer gamers, as you mentioned yourself. They do not know much about Nintendo's past or how the competition became big, they are new to gaming.

I don't really like what Nintendo did myself but I notice that it's always the same. They are successful when they aim for new customers and family (NES + Wii). I don't believe people who loved any of the earlier Nintendo consoles really defend Nintendo all the time and praise the Wii beyond heaven. Maybe some games that don't feel party-ish or remind you of great games in the past.

I don't get it. Why isn't Sony allowed to have Nintendo?

Errr, ok.

Were you not around when the Wii was getting bashed to hell on the Internet?  It sold the most consoles and was still neglected by many third parties.  Meanwhile the PS3 came out with a launch lineup that wasn't really that good, a price that was too high, and a new architecture that developers struggled with.  Yet people still bought the console and developers still supported it at their expense.  If it had been any other console but the PS3 it would have been a complete flop.  So who got the free pass again?
