Me and my buddy are looking for another f2p to start and play through together and was hoping my favorite forums could give me advice..
I've played Lotro and Guild Wars in the past, so not them.

I want
-Free play
-Real PvP (not Lotro's monsterplay)
-Low system requirements (WoW/Guild Wars graphics)

We just got a pretty big group here to start playing http://store.steampowered.com/app/113400/ recently. It's free and it has realtime, third person shooter combat. It's system requirements are pretty high though, but you could at least try it and see how it works.
