Metal gear solid - at some point
Tetris:axis
Dead or alive or street fighter - people been saying dead or alive is better, hopefully a mortal kombat will come at somepoint
Mk7
Heroes of ruin - maybe

This is a weird subject. It's just simply something you have to get used to. I'm so used to the 3DS/DS grip and feel, that when I play my friend's PSP, my hand cramps terribly.

To me, it's too small. Heck, I was raised on those rectangular Nes controllers so I should be comfortable with anything. Just not the case with the 3DS. Not even sure why. I never had a problem with any of the DS systems so why is the 3DS such a problem? Maybe I play it longer. I don't know. Anyway, with the Circle Pad Pro or my CTA grip, the 3DS's smaller size is no longer a problem. It doesn't look as awesome but it's comfy as hell with an add on.

Pick up a protective case. Adds only a small amount of bulk to it, but between protecting it and making it SLIGHTLY more comfortable in your hands (due to being slightly bulkier), you can't really argue with that, y'know?

Pretty good advice on not clutching it to the extreme. I found out that when playing that I have to adjust the way I hold the system till I actually get it in a decent position that doesn't cause any strain. Mario Kart 7 is the main game where I had to adjust my grip or it would feel uncomfortable. Hard to explain how I changed my adjustment but I believe it was mainly my left hand being out of position on the circle pad and trying to hit the L trigger button.

3ds is a tad small feeling for my hands as well.  I would highly suggest getting the circle pad pro.  not only will the unit fit your hands wayy better, but if you want resi evil, its the way to go.

Funny that circle pad pro was a joke when it was first announced but now that people have played with it they consider it a better fit.  This is probably coming from a lot of big hand users that put the tiny Japanese hands to shame.

I haven't seen the Circle Pad Pro in any store.

@Level1Death It's only available at Gamestop, but you can buy it online or from Nintendo. It's worth it for playing Metal Gear Solid 3D(can't really play without it) and improving your movement and shooting in Resident Evil: Revelations(I kill lots of enemies this way).

@MegaDrive08 You can download an arkanoid type game called AlphaBounce, it's $5 and has RPG elements. It's has endless amounts of levels...

Also there's Alleyway($3) on the Gameboy, it a small game(not sure if it's good), but it has Mario!
