Well, aside from the US, there's Europe and here, 
female characters are highly undesired. At least 
at the capital in the JB Verheydenstr. 29. I'm 
very displeased about males being so expensive. I 
don't really care about female characters as I 
somehow dislike women.

As far as I'm concerned I only see women for free 
and men for what you buy 2nd hand cars for. Any 
great Miaka cel or whatever "Girl from a show 
with pretty boys in it" will be thrown at you for 
peanuts, while guys go for what I spend for a 
PS2, chipped, with all accessories and 3 brand 
new games. Often, I could add a fitting TV with 
DVD and video in it + designer TV furniture.

In anime, thus on cels as well, females tend to 
be perfect beauties. And perfect beauty is what 
gets the eye fed very, very soon. In other words, 
they may get boring. 
While males, if they're not a creep like Hotohori 
or Yuki Soma, they have little flaws that make 
them atractive. Beauty like an anime girl's is 
often superficial and once you're used to her 
beauty, she'll look dull. 

Another theory of mine is that girls are 
generally more into anime, especially into 
collecting less useful things (I count myself as 
well here). Girls (girlish *shudders* ones 
especially) tend to only care about looks, same 
goes for male anime characters.
Also, male beauties are harder to find than 
female ones.
Plus, collecting has something sentimental and 
girls are usually more prone to that. 
And what else counts, men are more reasonable at 
that point (proven by girls running around 
SHOPPING "OH pretty, must buy!"). Men won't fight 
like idiots about some cel with breasts and long 
lashes on it as much as girls about some guy like 
their lifes depend on it.

Adfundum.
