I remember the first time I played that game on PSX that took gaming to an era in which it was not afraid to show it could make good use of some resources that were originally used on films. But that wasn't it all. I remember it for being really immersive. Developers had done a great job making small little every day things part of the actual experience, like the smokes to discover the alarms, the way the chick moved her assets even when she was undercover and how that was important to discover her, the god damn diazepam and his effect on the long rung...

I know, i know. You are a big Metal Gear Solid fanboy, one of those religious fanatics and you are very defensive about the subject of my thread. Chances are Sony's consoles defined the gamer you are. You won't agree with me. And you may have your reasons.

I was saying that Metal Gear Solid, as I remember it, was an immersive experience. Suddenly the logics you use in your everyday life could help you to do well in the game. When I first bought my Wii and tried Big Brain Academy and I had to use my wiimote as a phone to memorize all the food some imaginary costumer was ordering me, or when I had to answer the Travis Touchdown's blond weakness by a similar logic, I couldn't but smile in joy, as a child. That was something I couldn't have dreamt in the early nineties. When it happend, you can imagine, I thought how great it would be to answer the colonel that way.

Well, here we are. I was thinking, with the potenciality the new controller has, how great it would be to see Snake making great use of it.

What do you think about this? What kind of use could Metal Gear Solid series (or Deus Ex too, why not) of the Wii U controller?

What great uses could Snake make of the WiiPad?

Name me some, and I will agree/disagree on them.

Hack electronic devices using the screen.
Use the controller screen as thermal googles.
Hold some explosives really really carefuly so they don't fall and do something with them.
Take photos that accomplish certain features.
Write answers.
I'll keep thinking.

The only thing Snake needs to do is roll with the X button.

Put this in the hands of Kojima and watch the magic happen.
-Thermal vision on the TV screen when viewed through the controller
-Off screen view of hidden shit (like the Sorrow in MGS3)
-Codec conversations without going to a sub-menu
-Mine detector
-Controlling a secondary remote device (possibly by another player) like the MG Mark 88
-Night Vision
-Keep an eye on your secondary NPC while they accomplish a goal (like Stillman or Emma)
-Spot "Ghosts" like in MGS1

And that's what I came up with in four seconds off the top of my head--and I'm a self proclaimed idiot! Imagine what Kojima could come up with!!

I agree with a lot of this, and a lot of what d21 said.

Would be like the definitive MGS...

You gave it better quality thinking than me... and that makes me... 

These are all cool.

But every time Snake pulls out a gun I'll wish I had a wiimote.

I would love to use the controller as the infrared or night vision googles.

Or if the developers are being lazy, I would be happy with item/weapon management along with the mini map being kept on the 2nd screen, freeing up the TV screen.

The suggestions both the OP and D21 shared have me believing it'd be great, let alone all of the concepts the development team would come up with.

Even something as simple as having codec conversations on it would be very cool.
