seriously, i like them....
along with playing nintendo games, as a kid, i was into a lot of pc gaming(wc, cs, sc)
NOTE-steam was a lot harder to add a friend back in the day....way harder than adding someone on msc
and my friends were into the 1337 talk back than and they created usernames like
with zeros that could be the letter 'oh' or vice versa and it was quite annoying(don't forget this point if you choose to debate over friendcodes(and even than don't be an idiot about it))
a friend code is relatively easy, just write it down, enter it on your wii, and presto just like that you have a friend, now how many friends do you plan on having, even the most would typically be like 20, unless your someone that brags about fighting other people on wiichat like lik or shoko
now i probably have about 50 phone numbers in my cellphone, and i don't ever recalling about me thinking how inconvenient putting the number in my cellphone is
so really? what's so bad about friendcodes?
