Add me to the list of people who are shocked at the extremely negative reactions. Why do I like it? I'm glad I asked!
1) I love Nintendo. I also love RPG's and some TPS's. This combination hasn't been present on a Nintendo platform (nor possible really) since the SNES days (where TPS's couldn't exist yet). Now, Nintendo has finally released something which can accommodate their fans who love their stuff, but also want to play new titles with HD and M-rated material. Has it taken them a long time? Yes. Does this being overdue mean it's not a next gen console? Maybe. Have they fixed a mistake which needed to be corrected to even attempt to reclaim the hearts and minds of hardcore gamers? Absolutely!
2) The idea of the controller itself is great! It's lightweight (according to reports), has proper dual analog, face buttons, and double back keys. All of these are necessary in order to play any modern title which is developed for other consoles. However, it also contains things which haven't been used (extensively) in the context of home console gaming, such as the touch screen (which I wish was multi-touch, but oh well), the camera (which I will agree has been done before, but never as a part of the driving point for the console), and the speakers (again, done before, but never as a part of the driving point for the console).
3) The ability for the controller to play the game is astounding. While this doesn't affect a lot of older gamers who own their own homes and TV's, many younger gamers have to give up their games when someone wants to use the TV. As Nintendo has pointed out, this problem is completely averted by WiiU. Also, for those of us older gamers who this doesn't affect, at the very least it's neat! We are holding in our hands a display which can run HD video games and use normal controls, rather than having to take the iOS route of constructing touch screen controls for everything!
These are only opinions, but if you disagree, I'd love to hear feedback. One other quick thing, I'd like to share my reaction when I realized that Arkham City and Assassin's Creed were coming to the system:
"Nintendo will be rolling in money. With the Wii, they expanded their own gaming market, but in return they had to offer a non-HD, non-hardcore gaming experience. So they made a reeeeeally wide pool, but it was rather shallow. With this console, they've added HD and normal controls (to an extent), which allows the 3rd parties to bring multiplatform titles to WiiU. In other words, Nintendo can now sell this console to casual users just like they did the Wii (and it will have more Wii-like content for sure), and can sell to hardcore gamers by having proper 3rd party support for multiplatforms and exclusive IPs. That pool just got really deep, and Nintendo is going to make a fortune..."
Maybe it won't happen, but that's my take on their marketing strategy atm. What do you think?
