HTO is a well received mini-mod which overhauls the original game's trading system and expands on other minor elements to improve gameplay immersion.
This is the Master Edition compatible with the Complete 2009 mod. I figured some people would want it. Also, in my other download file for the vanilla Master Edition, the readme says that it is compatible with complete, it is not, period. It has been reported that the realistic weapons add-on for complete may cause a game crash if you try to use it with Complete and this mod, so if you wish to use this mod, please don't install that add-on.
