I am not only talking graphics, but graphics very much are a huge part of next gen.
If they weren't then, why bother upgrading from a NES to a SNES?
That is only one aspect though, and the Wii is behind a generation in several.
It lacks digital surround sound. It lacks processing power, which goes into things such as physics. It lacks ram which, can limit the size of its worlds, or at least what you can see/access of them. It lacks storage space for those nifty downloads they do offer, and prevents options for other downloads that other systems will see (Rock Band on the Wii? Have fun missing out on the massive amounts of great downloadable content).
The Wii does have an alternative take on gaming interaction, in a sense that is next gen, but it is almost all novelty, and it isn't anything that couldn't be done on any other system with a simple add-on.
Once you are into a game, if the controls are great, there isn't much thinking about them, and as such... There hasn't been some underlying need in gaming for a control revolution.
Gamecube games look just like Wii games (mostly... The Wii does at least have 16x9 support). They just happen to control like every other generation of games, which has been fine.
My point was not to say that the GC had ugly gfx. It didn't. My point was simply that there is hardly a generation gap between GC and Wii games. The only gap that is there is one that was never really an issue anyway, so playing GC games on a Wii doesn't feel at all like playing old outdated games in comparison to playing Wii games.
That can't really be said about Xbox and PS2 games played via BC on their successors. 360 and PS3 games definitely do make those games feel dated.
Now... I never asserted anything about a Wii being a system useless for playing anything but old NES titles, so I will just chalk that up to you replying to someone else.
Actually, I was responding to you thinking you said the Wii was only good for NES titles, but I went back and realized I misread. So I'll take back that you made that comment.
Far be it from me to argue the fact that Wii is the least powerful system of the current generation. And yeah, when it comes to "next-gen" content, they're lacking in spec sheet buzz words. But let us rewind to page one of this thread where we were discussing Sony and their current third place position (especially when they could have had first oh so easily). That's where all this discussion comes full circle. Despite the lack of, as you said, digital surround sound, processing power, ram, storage, graphical, etc., Nintendo's still currently holding the top position in worldwide sales (
source). Sony, swimming in most, if not all, of the above... last.
And perhaps the Wiimote is a novelty, but a novelty that works quite well when the developers use it wisely and not abuse it (on the flip side, there are some games that tack on needless Wiimote interactivity). The hardcore controller jockeys may scoff at it, but non-traditional gamers (e.g. - my girlfriend, her friends, their parents) love it to death. So perhaps that's Nintendo's idea of "next gen", bringing games to those who normally wouldn't play games. Doesn't seem to be hurting their bottom-line.
And here's the thing: for the traditional non-gamers (and gamers trying to get non-gamers into gaming), there WAS an underlying need for a control revolution. Back in the days, games used to be "pick-up-and-play". Now, suddenly, we're jockeying eight to ten different action buttons while maneuvering two control sticks. Playing a new game means spending a good half-hour in some tutorial just to learn how to jump. Nintendo wanted to bring gaming to those without the patience or ability to know which of the numerous face buttons executes an action. And they did a pretty good job.
By the way, don't think I'll be playing Rock Band on the Wii. When it comes to certain games, the XBox 360 may be a better choice. I'll agree with you there. There are games that are just crying for a powerful machine to be used, and I'm not discounting the purchase of another next-gen console for more hardcore gaming.
Reading back, I think somewhere along the line there was some derailment of discussion when we were talking about backwards compatibility. That's most likely my fault. So let me bring us back to that. Despite the graphical similarities between the Wii and GC, a library of games is a library of games. There's a possibility PS3 owners never owned a PS2 or PS1 and Sony cut out a large library of playable games from their struggling system. They can stand to be making back their losses with PS2 software sales*, but instead opted to make the PS3 less versatile. Not a great move from any standpoint.
(*I believe the PS2 outsold everyone during the 2006 holiday season, so I admit the money Sony could make from PS2 software sales for PS3-only owners is probably not as great as I may have made it seem.)
