I was never really a Nintendo fan, and they've done nothing these past 10 years to make me one. I'm more of a single-player guy, I really do appreciate good stories and aesthetics in games, and like Pitch said, I feel like their stuff is mostly aimed towards pre-teen kids, families and party-gaming people. While their games are undeniably fun(they must be to get so popular), that's their only merit. But the way I see it they've been milking what few IPs they have to death. What do they really offer(this is not a sarcastic question) besides Mario and Zelda? And their spinoffs? They had success with the original Wii and (in my opinion) its gimmicky motion controls largely because they were the only player on the field, but that's largely done. I don't believe the Wii U will be nearly as successful. It has the same problem the PS Vita still has, a lack of really interesting games. You can't sell a console without several really good titles for it. I thought Sony knew that with the Vita, but apparently development has been slow. If they do it right cross-play with the PS4 could be huge, but I have my reservations.
And Nigma can be harsh, but then again we all can xD
