I have really never played solo since my wife plays also. We played EQ together even when I box on EQ she still played along with me non-boxing. Even with wow, I can run a heroic with my team or sometimes she brings one of her alts along and I swap a shaman out for her. I also get the benefit of her being in a rading guild so I can bring one of my characters along if they are short or lacking players that night. In PVP tho I am on my own ;p .... she hates pvp.
