Ok, just looked at it for a minute, if you sell the template of it you can make maybe 20 dollars, off 1 person.
if you sell the whole site, like others said it has no visitors, if It had about 50-100 unique a month that would be at LEAST $ 400.00-$ 800.00
Edit: If you had just the perfect reason for someone to buy it, and showed them what they can do with it, .... ( Me )....I would not mind $ 400.00, though I have figured out how to make my own sites like that so, sorry.
Good site, just set the reason for why people should buy it, and well its sold for a minumim of $400.00 .
How I make money, make sites like that, put them on a forum for a game like travian.com, alliance members or leaders would buy it, (Yes I do play it, if that was not allowed feel free to delete this post).....working on a site for just the gameing company to bring in some big bux.
Good luck selling your site.
