kuebk: Gothic series is completely linear.
that's not true. there's plenty of side quests and things to do. yes, the main plot and progress of the game is fairly linear, but even that changes completely depending on which faction you choose to join and becomes linear later in the game.
gothic 1 has funky controls, but in terms of story and continuity gothic 2 is better when you already know some of the characters and the lay of the land. overall #2 is a little bit better, especially in terms of controls, inventory, and general interface, but both are good.
