Like any RPG, item collection in Legends of Aranna is a big part of the game - so big, that Mad Doc had to expand the player's inventory space by creating a backpack item. Once equipped, the backpack increases your carrying capacity by exactly 54 per cent (hey, the guys at Mad Doc are precise). In addition to the backpack, Davis also worked on an auto-arrange algorithm, which ensures that if it is possible to fit an item in, it will fit. No more playing Tetris for the optimal arrangement of equipment.​
