I know what they're saying really. I thought that about Nintendo for a long while that they're aiming at kids, and obviously that will be putting off developers making mature games.
A problem for Nintendo that won't be so easy to fix. They really need to try getting a lot more mature games onto the Wii U/3DS to demonstrate they're for mature gamers too.
Sometimes they've demonstrated mature games are wanted too though, such as Resident Evil Revelations, and MH3. I think it really is just Nintendo's place is being a secondary console mainly atm, and only the real gamers will be wanting it funnily enough. I don't think people will be looking at Wii U's for a primary console unless they're a pure hardcore Nintendo fan and simply nothing else interests them at all or just don't game so much that they don't need another console.
I'm just looking forward to how Nintendo try and fix this for next console, or whether they plead ignorance again and pretend every things fine. One thing's for sure, they just have a lot to prove to me, I probably won't buy at launch no matter what they show, cause Wii U seemed fine leading to launch, but that was because of lies too. I remember reading there was going to be an achievement system and there wasnt.
Nintendo did this to themselves really. I do love a lot what they do, but I also hate with a fiery passion what I don't like and most of the time its not such a difficult thing I'm asking. More so for a company of Nintendo's size. I think the Wii U will be cool at least for a Nintendo Box this gen, (Hell if it wasnt you'd know it was bad), but we got a few awesome 3rd parties too like Bayonetta 2 and X, which is at least a step for Nintendo.
