I know it's a joke (I assume) but ignoring that those dreads look like trash, the OP is a male and that's a female only hair style.
Also it has nothing to do with engine limitations. Sure, certain hairstyles could be hard to pull off with the way things are, but not all hair styles are the same.
Not one of these hair styles would require anything the game doesn't already have.
And of these the only one that might be a
problem is the last.
Not trying to debate or anything, just pointing out that we don't need to make excuses for them.
Fact of that matter is that for the past 5 or w/e years most of the new hair styles we've gotten were from the Player voted winners from the hair design contest.
And as a reminder ...
"Aspiring aestheticians from across the realm have been submitting their unique and fancy dos,
and the development and operation teams have shaved downed the entries to 25 of their favorite hairstyles for both male and female. Now the time has come to see who will make the final cut! Submit you votes for your favorite entries and decide the winning male and female hairstyle!"
They narrowed down the selection themselves to what they thought was most interesting which means
that all the long hairs in this thread and
these 2 were things they felt they could do 5 years ago. Only about 2 years now have they been making legit HQ hair and with Viera they have shown how much they have improved with hair and face modeling.
Player base screwed us and 5 years later people are wondering why we get so many short hair styles after the player base voted for them. So yeah, we don't lack options cause of engine limits.
