Inventory Systems

In my survival game I'm building in a new inventory, so I thought I would study other games. One of my favorite types of inventory is a size based system where objects sometimes take up more than one slot. This forces the player to really organize everything so it could fit. This type of inventory is most popular in survival games, but could be used in other types of games. Another type of popular inventory is a stacking inventory where the player could stack small items on top of each other, making the inventory much easier to navigate. Minecraft uses this, and it works well because of the large amount of blocks you have to carry around just to build a house.
