I've been bringing my Nintendo 3DS with me everywhere to demonstrate it to family and friends. Without fail the game I help to demonstrate its abilities with is the Steel Diver submarine game.

Steel Diver has three separate parts to it, but the part I load up when I hand the Nintendo 3DS unit over is always the sub hunt part. In this mode, the 3DS acts as a periscope. You can literally turn around in 360 degrees and see the subs all around you. It's amazing. The 3D effects on the screen are impressive, you rotate with the periscope, you hit the button to fire your torpedoes. You can submerge to dodge their torpedoes and you tap the screen to repair any leaks. But really the keys here are the full motion sensing of your turning and the depth perception. It is really cool.

There's a strategy game too, where like Battleship you move your units from square to square and try to kill off the enemy. The game is certainly a lot of fun, but it doesn't show off the capabilities of this new system nearly as well.

And then there's an arcade style "navigate the depths" game where you are cruising along underwater looking for things to kill. Again, it's fun, but not with that "amazing" reaction you get from the first game.

I gave given Steel Diver with the sub hunt mode to countless people - both gamers and non-gamers. They get the task immediately. They turn around in place and the game view rotates. They hit the buttons and torpedoes fire. They can see the 3D depth. It immediately gets them to understand just how amazing the 3D system is. I'll comment that one person so far has gotten a headache from the 3D effect but that is the "fault" - if you can call it a fault - of the Nintendo system, not of the game. Everyone else has adored the game and how it works.

In terms of not showing the system to friends, the battleship style game is also tons of fun. At home we play that one quite a lot. It's a good logic puzzle.

Well recommended for anyone with a Nintendo 3DS. There aren't buttons to learn or complicated rules to memorize. You hand it to someone, they turn around, and they are hooked.
