Rule of '99
Players are limited to a certain number of each item. The number can vary based on the
item (for instance, you can have only one weapon) or its effect on the player's load. As a
rule of thumb, 99 should be the maximum number. However, it's up to how your game
will use the item to denote its maximum number.
In the Final Fantasy series of games, Rule of '99 was used throughout its inventory sys-
tem, allowing the player to carry no more than 99 potions at a time or anything else for
that matter, as shown in the following screenshot:
