If you're familiar with the sandbox mmo EVE Online you might like Empires of EVE. They're very well put together and very thorough historical accounts of some massive and long term player driven content/conflicts throughout the history of the game. It was so much fun to read about why my side's leadership made certain decisions and about the other sides' perspectives of some of the space wars I was part of when I still played.

Oh man, I'd really like a copy of that and I see they have a sale on ($40 for both hardcover volumes), but then... $50 for international shipping is a bit steep.
