Top Ten Secret Player Bases and Strongholds

Your Castle (Suikoden series)

Most JRPGs involve a heroic journey across the world, but the Suikoden series embroils you into warring city-states, political upheavals and large-scale battles on top of the usual adventuring fare. Attracting 108 part members and NPCs to your side is a main component of each game, and early on you're given (or capture) your own castle to populate with allies. 

The Suikoden games are full of memorable moments and epic battles, but some of the most fun I had was simply wandering around my own castle talking with allies and participating in various mini-games and events.
