He's ideas make perfect sense. What most of you are not taking into account. The Wii mote decides on what kind of experience gamers are getting. So if sequel has you doing the same waggle you were doing in part 1. New Wii gamers are more likely to stick with that older game. The content it self doesn't matter. The new Wii audience cares about the experience. Take Mario Kart the first Wii wheel game, Wii Fit first exercise game, and now Just Dance. A very new dancing experience for Wii. If you can't do something with the Wiimote. That makes it worth upgrading. The new Wii audience will not care about it.
That's why Wii Sports Resort is selling well and Wii Fit Plus not as good. Motion Plus make Resorts a new experience to Wii Sports. Wii Fit Plus is just Wii Fit with more modes. You can't do what you can do in Sports compared to Resort. Yet you can do everything in Fit you can in Fit Plus.
The New Wii audience has a fresh view of gaming. They have not been brainwashed like the pro gamers aka core. For all the past years.
How many of you have bought Madden, Street Fighter, and other games. Year after year only to get a few new characters of a new gameplay gimmick. A true Sequel is a continuation by number or plot. Yet is a totally new experience. Resident 3 to 4 to 5. Yes they are sequels, but are totally different games. Wii Gamers don't want Mega Mans, Street Fighters, and Madden. The same thing only with minor upgrades or changes. Adding modes, characters, and items. That could have been in the first is not going to cut it.
