Don't worry Odysseus, there are a lot of people who play on gameranger, but they are more spread out. There are far more people online mid-day than late at night. I'm frequently online as well, so you shouldn't have a lack of people to play with
Here is my list of friends alone: Adis, DarkRadek, Draco10000, Haman, Legolas, LEO, Nuggets, Sawman and DevilsDaemon, and that's not counting the 20+ randoms I have played with.
I'm glad to finally see the reasoning for having Tuungle as the main network, I was very curious why, but I understand now, looking at it from a new players perspective. As somebody who has played extensively on both, I can safely say that gameranger is far superior, at least for me. Less lag, less disconnects mid-match and the players are a lot less........ stuffy? I don't know, on tuungle people never seem to want to work as a team, and a lot barely speak any English at all, so its not the best place for me to play.
