I think you should wait for higher offers, not just because I think you can get higher offers for the name, but because you just got it and already have that offer...you don't know what's out there after having the name for just a short period of time. Game/Games/Gamer/Gamers/Gaming with Weekly/Monthly are all taken in .com, with some .nets taken (including GamerWeekly.net). So immediate viable .com alternatives are not available, and thus someone may be willing to offer you more than $100, maybe up to mid $xxx. I personally would rather have Gaming or Games weekly, but still, that's a nice name for a newsletter/e-zine for video and computer games. Good luck!
