eGO all the way for me. I maybe playing in other servers but most of the time i put eGO tag in front of my nick. (Most of the time because some games doesn't have clan/guild stuffs. I am not saying i am extremely loyal to EdgeGamers, it's just i feel there might be some sort of conflict of interest or whatever it is called.
And EdgeGamers is the first community which doesn't auto-kick players like me, who have slow internet connection / high ping.
I play on another minecraft server (im a moderator), since the one we have isn't up to my standards, and it takes a long time to process stuff. But, I still love eGO! Its just I don't like it taking a month to decide on stuff :/
I'm also part of a guild(points system that gets you more powerful) on mgftw because they have L4D2 servers that I play on a lot. I think they have CSS and BF3 servers but I don't play on them.
