The first video game about Lost equipment was released on October 2, 1987.

Ubisoft, Sega and 2K Games has published most of these games

In some cases they can somewhat trivially re-attain them, but this is not always true.

Cases where this is obvious, such as the player acting as a soldier, police or such on various missions should not be considered for inclusion as personal "acquisitions" are not generally tolerated in such and is therefore to be expected that they don't hold that fancy bazooka they had in last level/mission.

Some games also reduce the equipment at spots where it makes little to no sense, and therefore are viable for this (this should be noted however, as it's a border case).
