There's always one little thing about a system that just drives you insane or just stands out and bugs you whenever you think about it. What flaw in the system is that for you and what would you do to improve it?

To me, it's the spacing of buttons on the Wii Mote. Reaching from the A button to the D-Pad just feels awkward to me, even with my decently sized hands.

I think the controls on a Playstation (1) are so weird and confusing. Plus the shape of the controller is very uncomfortable.

The 3DS' Circle Pad NEEDS more grip to it's surface. Your hands sweat after playing too long, meaning your thumb is more likely to slip off the pad. It's probably one of the only flaws of the game system, as far as I know.

Everyone that's not Microsoft: Put the Analog Sticks on line with the buttons. It's more comfortable that way.
Nintendo: A wireless controller that doesn't have to be hooked up to the stupid Wii Remote with a cord. (I think the Wii U controller thing does that )
Nintendo handheld: YOUR SHOULDER BUTTONS SUCK. FIX THEM.
PSP: Everything was good except for the games. Wait what? Exactly my point, the UMD ruined the experience. Everything else was good. Oh wait, no. The stupid failure of a circle pad was also bad.
More Nintendo: Be like your competitors. Get rid of Friend Codes.
Everyone: A Start up song like what was on the PlayStation would be appreciated. It made the system feel a lot cooler.

As God of All Gaming Systems, I would erase the Kinect from mankind's history, as nothing but sin and shame has come about it.

Get rid of apps. You're on a ****ing game console, don't pretend it's a computer.

Quit making every game hold my hand. I can figure out how to freakin' jump and shoot on my own by pressing buttons.

In terms of modifying a game system permanently for every system, I'd change the volume switch on the original DS and the 3DS into a rocker switch. Rocker switches seem easier to handle for me.

In terms of changing games, I'd add a mode called "Alright, I've played this game before, don't make me do 50 million tutorials I already know".

DS, Wii, and newer: No Friend Code and the rule "do not share Friend Code on the Internet" on most instruction manuals. We are not kids anymore.

Letting me able to skip tutorials, especially for sequels.
Same for sites like Facebook and Google [service name], where it makes he feel like an old man is trying to teach me how to catch a Pokemon.
Also, the fine print of "You must read instruction manuals" is useless.

Flash and mobile games: some games are so innovative (or using a word with less bias: different) that I need a tutorial, but due to lack of programming, some tutorials are too boring (too much text), or has no tutorial at all.

Nintendo, modernize.

Play DVDs, get friends lists, give third-party developers a chance. Oh yeah, and get HD graphics. It's not necessary, but in this day and age you gotta get with the standards.

My suggestion to Nintendo: please improve your internet speed. Everytime I try using the Wii Internet Channel, webpages load dreadfully slow. It might just be because they only allow use of Opera? I don't know. I'd also like to see the ability to have whatever preferred web browser I want to use on my console.

Game Freak: That "Don't switch your system or else you need a new Friend Code and your Pal Pad is erased" thing? Get rid of it. Updating and spreading my FC to everyone after I deleted it is a hassle.
