Moving a character with infravision into a dark area automatically turns infravision on. It is possible to select an option so that if any character in the selected group has infravision, such a view is used on the screen, instead of having to select the actual character with infravision. We felt that adding complexity to the monetary system would not add to the gaming experience. Only so many items fit in my inventory spaces. Not only are there gem bags and scroll cases to hold your many gems and scrolls, but there are also bags of holding that can hold the larger items.
Money is kept in a common party pool and has no weight.
Extra objects can be left on the ground, but sometimes NPCs or monsters come around and help themselves to those items. Objects stored in containers, like chests and cupboards, are safe from these scavengers. There are both mechanical and magical traps. The traps on the floor have been changed so that they will only take up a portion of the space and don't cross the whole corridor anymore. In Baldur's Gate, characters had problems navigating small passages and staying in formation.
