Ultima 7: The Back Gate & Serpent Isle

Considered by many to be the best games of the Ultima series, Ultima 7 is one of the most detailed and time-consuming RPGs I have ever attempted to tackle. You can pick up and interact with just about every object in the game and there are tons of dialog trees to navigate through. The story is intriguing and branches all over the place, with some of the main plot lines spanning both games. My biggest complaints with the game is the awful MIDI based sound effects, major Windows compatibility issues, and the fighting system lacks any strategy. The game makes up for these flaws in its depth. The game is less about building a character as it is about unraveling the mystery of a strange religion known as the Fellowship.
