Part of what made the past few gens have a main console that was well looked upon was due to the fact that there was no competition. You look at the PS2. It's competitor was the GC and Xbox. GC was mainly being used by Ninty exclusively and alot of games passed and went to the PS2. Xbox came along later and devs weren't familiar with it, and it's popularity wasn't big with the Japanese crowd.
These days we have the 360 and PS3 basically on the same page where almost all games come out on both unless they are thrid party (although alot of Japanese games still are ps3 exclusive due to the fact that the 360 isn't popular in japan like most Nippon-Icchi, forive my spelling, games). Basically exclusives give a platform it's identity, I think when we al look at 360 we see halo, when we see ps3 we think uncharted or GOW or some other game that we are all waiting for to come out (LG, FFv13).
Nintendo has always had a strong line of exlcuives but only started to bring some of them out in the last year. Where is Star Fox? I think we all know that the wii-mote would have been perfect for controlling an Arwing. You go to gamestop and look at the wall for the Wii, how many games catch your eyes that are being overwhelmed by the shovelware?
What the WiiU needs to do is put the characters we all know back into action. Now I know what made the PS2 popular was it's third party exlcusives which is mostly a thing of the past due to the ability of more than one console that has a large install base but this could allow some publishers to do thing that they want to with the new controller which should be given a chance. What also needs to happen is Nintendo needs to start some new IP's. Weather they are from a 3rd party or in-house they need to happen so that the WiiU is seen as diverse and not just a home for the cartoony characters that we all know and love. That is what made the N64 and PS2 successful, their diverse libraries that were grounded by franchises that became synonymous with the company. The WiiU will never get the exclusive third party support the N64 and PS2 did due to the reasons from before, but it can definately emulate it with new and exiting mixed in with the old and good (NO, do not mix genres! We do not need RPG Samus or Star Fox Racer) I mean a mix of games.
And although I do hate the name (WiiU? Are they walking into a daycare and picking the first think they hear a 1/2 year old say?) we have to look past that and realize that names like N64, yea I know it was named that for it's 64 bit CPU and it wasn't just "N" it was Nintendo but who cares? It sounds stupid, like it was the winning call at a BINGO game. And Xbox? WTF is that X for? I heard it had to do with Direct-X but again who cares, it sounds stupid like it is an accessory for prostitutes or something like that. Playstation is the only one that makes sense. And things like Saturn and Genesis and all that other jazz sounded cool and then there were the ones with numbers that were like Akoriama 7000.2347, like WTF IS THIS?!
In short, the WiiU needs to put the DO back in NINTENDO! And maybe we can mash the two names and get WINTENDO!
