I am not sure what you mean, but here is a PC-only spot I like:
A great site for maybe the best PC online gaming ever is Runescape.
www.runescape.com
I have been playing for 3 years. It is much better than WOW as far as gameplay goes... it is harder to level you character also, so I feel it is more rewarding. Anyone can max level in WOW. In Runescape it is a big deal. Runescape is free to play or you can opt for expanded gameplay for 5 bucks a month. PC's only so everyone is pretty cool. No snot-nosed console dummies clogging the place up.
