For me, SP games need to have a good story (Thief series, The Witcher), that makes it feel sort of like I'm reading a book, but with influence over what happens and how. For strategy games, I like co-op games and I'm very much a sandbox style player, so I don't mind single player at all. I play far more SP than MP, though playing against humans is more fun than against the AI, especially in something as deep as Dominions is. The time and organizing things are usually the main stepping stones, especially since I have so many commitments to so many different directions.
