It is definately a mixed bag across the internet in regards to the Revolution controller. These seem to be the big complaints...
1. Not enough buttons or control sticks.
-Turning motion into input reduces the need for buttons and analog sticks. Current games use too many buttons as it is making you fumble over the controller. Simple = good.
2. How do they expect you to play
-The popular fillers have been Madden, FPS's, and so forth. First off these people need to get out of their shell and realize there is more than one way to play a game. People need to stop thinking about how they couldn't play their current games with the new controller. Its new! Give developers time to develop their flagship games for the controller and you will see NEW ways to play your games.
3. All it is good for will be Duck Hunt 2.0
-Wrong... it means playing old game types in a new way. The market and various genre of games have become alarmingly stale the past few years. It has been more about sequels than originality. Any game on the Revolution is going to be a new experience for a while... it will be inventing new ways to play games. All because of the controller.
4. It is meant for Japanese gamers who like sword swinging and knick knack games.
-Sorry... this thing was built to be fun. If fun is limited to Japan... I may be moving there. People are sadly taking the tech demos as real games... believing the controller only works for the applications it was shown in. With developers there will come FULL GAMES built around this controller. Give it time people and let the developers do their jobs.
