Myios.us feezr.com orblist.com labreve.org rpgolds.com jokiart.com - fake pr4 askrank.com Would appreciate your honesty.
I don't see any valuable domain name in this list.. With .us extension only popular words with business value can give you money. In .com extension only dictionary word has value. PR domain, think of higher than PR6 to sell at good price if DA and PA is good with good keyword in the domain name.
AskRank.com You could create a stats service that shows the Alexa Rank , Page Rank and so on. RPgolds. I think it is suitable for selling games coins. For the rest, I can't see any utility.
