The final major change lies in Thief's mission structure. As before, Garrett has a dozen or so major missions, each of which takes a couple hours or so to complete. However, they don't take place one after the other -- the game is spread over several days, and in between missions, Garrett has the opportunity to explore the city he lives in. There is no special mission involved in these bits; instead, you're free to break into apartments, steal loot, and get involved in people's problems. Example: Garrett lives in a small apartment, and his landlord (as you find out if you pick the lock on his door) is being blackmailed by someone. If you want to help your landlord, you can hunt out the blackmailer and dispose of him, taking any loot he's got in the process; if that sounds too risky, then you're free to ignore the affair. The idea here is to nab lotsa loot in your spare time, which can be sold to the fence for thieving tools and other helpful on-the-job accessories.
