or it could be that the technology wasn't up to par yet to analyze our brain waves fast or accurate enough for it to be meaningful, much like how the 3DS is to the Virtual Boy. It's quiet exciting as technology improves and we are able to tap more and more into the potential.

No, it was a people problem, not technical.   Reading a brain wave is fairly simplistic from a technical standpoint (EEG has been around for nearly 100 years).  Training the brain to alter internal frequencies on the fly is not so simple and much more difficult when trying to actually play a fast paced game like Tetris.

Watch the TED demonstration on this product and then imagine trying to play Tetris with it.  It takes Evan 40 seconds just to perfom a single action (disappear).

I'm not knocking the product itself or the incredible possibilities it opens up.  Only that we've tried games before and we simply are not trained for that kind of activity.

He's also about 1000 years old :P I'm saying technology hasn't gone to the point where they can read things on the fly and analyze them in such fine detail that we can do these things instantly yet, and when we get there, it will be just like the 3DS where some people are okay and love it and some people will hate it, then there will be people that can't use the technology after calibration at all.

It's all in the "finer" details, but at least the possibility is there. Even EEG has advanced a lot since the cowboy days.

This is actually pretty funny because of how wrong you are. You're saying it takes longer to think about an action rather than doing it, yet every action is determined by our subconscious before it's relayed to our conscious to perform the action itself.

Then you take the hard example of disappear rather than the 'pull' action, which occurs (appears to) instantly.

Nothing like biased thinking to present nonsense.

The only thing that will beat the controller is virtual reality.

Another Kickstarter Project (I shouldn't be talking)

i don't think i would want to use something like this even though they look cool to wear. I just fear something like this could be used to control us one day even if that isn't the developers intention. Look at how governments try to censor and control the internet now (and often fail). I could be wrong but i'm skeptical of this kind of thing. Also, i'm not sure of it's place in gaming.

It is interesting technology and should have some great uses but i still have doubts on it. 

Even as a little kid, in the early 90s when people kept talking about VR as if it was, without a doubt, going to be THE FUTURE of video games (Oprah even had a whole episode about it), I never thought it sounded cool or appealing.
