The downloader/updater of the mod is resumable if paused/quit so if its not about a maximum download limit its not impossible :) In a way, however -altough it refers to it heavily- its not based in the world of 'thief'. The game world is still kind of free to form, besides some already laid milestones. http://modetwo.net/darkmod/wiki/images/b/b0/Bridgeport.gif Map builders could also choose to build out of this content however, its just harder to do it because most of the assets are based around this type of universe. Following its base-lines, but it got enhanced and varied a lot. -Time not stops while reading, you can also look around while reading. -Sound based lockpicking with settable difficulty -Rope physics, swinging, pulling down a box with your weight. -object manipulating, rotating objects. -expandable stim/response system that lets interactive objects work as they should. Candles can be lit from another fire-sources or put-out by any water source-etc.. and that list goes on..
