Nice name, not as nice as gamer.tv but good name anyway. Impossible to value without more details- how much was the offer you got? $x or $xxxxxx? Where is the traffic coming from? Is it old traffic from the site, or is it from promoting the name on forums like this. .tv is hard to appraise as its less well known to end users and not so many resellers buy it either, so it even more about finding that right person. I'd have a stab at high $xxx- low $x,xxx with current information.
