Language game wise is fickle, to say the least. When you're an Orc player, you have to apply the dumb dumb talk due to the tusks, but for some reason it carries on even whence you're speaking in their native race tongue, I always found that funny once I started thinking 'bout it
As for the wording we use, and the way we have our 'normal' talking Chars talk. I try and give my chars an accent. Most started off with the usual speaking English, then after a few years on the Island, they get kinda hill billy, at least in common. A chars native race should be pure and unfeckled in me own eyes
"Oh, you know what I mean lad? "
"Och, ye ken wha'd a' mean laddie? "
That sorta thing.
As for the cutting of words and whatnot down, it annoys the living ficklesticks outt'a me. Honestly, hi? HI? I know we ain't RP'ing a proper bloody time period. But there be trolls, and there be castles, and you're going to say hi, sup? I'mma facepalming all the while
PS: If a GM ever finds fault with how my chars happen to be speaking, or community managers. By all means, pull me up on it
