I'm an application developer and avid gamer. In addition to http://www.lmnopc.com/ , I also run a couple sites on the side:

WishListBuddy.com
WishListBuddy helps you save money on the stuff on your Amazon Wish List. Ever notice how prices drop after books/movies/games have been out for a couple days/weeks/months? With WishListBuddy you can set a target price, and when one of your items hits or goes under that price, the site will email you to let you know.

GameWith.Us
GameWith.Us is a social networking site for gamers. At this point it's really intended as a tool to give pre-existing groups ways of organizing online games, but I'm always adding things to it and some day it will be the ultimate destination for online gaming. I hope. lol
