well firstly you have the TM issue where if Rockstar wants to come after you they can, not good, pretty big gamble. Secondly, you have the fact that the period between gta4 and the last gta (vice city) was 5 and a half years. Not only that, but that was Vice City. If you go back to the last numbered gta, gta3 that would be 6 and a half years. SO basically you would be renewing these domains for a pretty long time before they made much value. So you would have to decide is the renewal of all four of these .com's worth renewing for lets be fair and say 4 years. So that would be 4 domains x 4 years = 16, times your average .com reg fee renewal. Right now it is around 9.99 but lets say you always find a discount and do it for.... 6 dollars. that would be 16 x 6 = $96. Are you going to make a return on this money? Are you going to run into TM issues? To me, it isn't worth it. But you have got to make that decision yourself. I would say that these are worth less then reg fee now, and if you use these .coms to make any money you are going to run into legal issues.... I hope that answers your question. And I have not been domain-ing long but I believe to know what I am talking about here. If I am someone else can come correct me.
