Ok, now I understand you a bit..
First I was like.. Are you cracy..
To have a phone number (friend code) system instead of a gametag, then you can have a name and a nickname you can use in games..
Seem to make sense..
Altho' I like the gametag system, as I use the same name on forums an email.

there a block feature for something.

first there is not a home-avatar like experience on the wii even announced,
no numbers are not easy to remenber gametag.

for one my psn id is myname+a number, less than 10 digits,
0602-6431-9626 than that.

at least you know who leekgeek is than 0602-6431-9626

most of the people will likely be the same.

now sony implemented a PSN underground site when you get a forum, and access to your PSN friends everywhere.

@EaglesEye: Ok, so let's see.

To your first point: You need to know someones friendcode only when adding someone if there's no in-game adding. After adding, you see only Miis and their names.

Your second point then again had nothing to do with friendcodes. Let's say that the system you described would be implemented in a Wii game, you would still see my Mii would be beating your score, not some random series of digits.

And for the last part, yes the code is different in every game. Actually, for example, Mario Kart Wii has four licenses, which all have separate friendcode (this is needed in order to make multiple online profiles possible). If you use the same Mii in different games, you'd be seen as the same guy in every game, no matter the friendcode.
So far the only bad thing is, that the friendcode isn't unified. Having your games friendcode linked to your Mii and Wii friendcode would solve the complaints people have. But, that has nothing to do with the friendcodes itself.

just accept bdbdbd that friendcodes suck and no 1 want them on xbox live. there is no problem with gamertags so y would m$ change somthing thats no broke

LOL.

I don't think it's funny at all.  There's a bunch of people in here supporting pedophiles offering up their points.

Actually he does have some good points. Friend Codes are a good idea, just implemented wrong. Also Friend Codes for every game is a bad idea imo. One friend code would be nice. It would be just like a phone number kinda. (:

well if were talking about pedophiles lets put friendscodes on are pc to so we can only speak to people we no and can only go on certain websites...... dont be stupid mate no every1 on xbox is a pedo.

That's a great idea.  Chris Hansen should get on the case.  Thank god for that hero.

I know not everyone sharing points on their Xbox Lives are pedos.  There are also their unsuspecting victims... duh.

@Jo21: Ok, then who leekgeek is? Nobody unless you know the person in someway. Same as the friendcode. Besides, you see only peoples Miis and their Miis names online. Most of the people are propably happy to know their real life friends online with the same name they are known IRL.
The M$ avatars are largely used (as i've understood) as Miis and they would be easy to implement on a friendcode system, where the avatar would be your gamertag and the friendcodes only purpose would be to verify the person in question (the only reason for the friendcode).

@Voyager: And the friendcode system is more accessible since you don't need to make a (random) name for you.
