Those are all good names, but as you probably know and were expecting to hear, the .info knocks down the value quite a bit.
I think you could get $xx for each name, maybe more.
eGamer.net sold for $300 in 2006, so I can say for sure that you probably aren't going to get more than that for eGamer.info.
But these are still great names and I think you can find a buyer. Good luck!
