I have seen a number of games where the inventory space that you have (e.g. 3 squares along the bottom) is not capable of carrying an item that is just oriented around a different axis (e.g. 2 squares up). Surely you should be able to collect these items and place them on a different orientation? I sometimes wonder where the game designers' imagination has gone. Sigh…

Something that I have seen in some games is the use of containers that can fit in your inventory and add to your total inventory total. I think that this is a good idea, or the character may also be able to find more backpacks that have larger containment. This would really make the game a new experience, and would add to some different items than are currently available.

To expand upon this idea, I wish to explain what I mean about the backpacks. You may pick up an empty backpack and have it in your inventory (we differentiate the two by 'inventory' is equipped and 'backpack' is not). You may not place any items in this backpack, because otherwise you can theoretically have unlimited space (recursive). You may change the current inventory container with a backpack, and any items within it will be swapped over. Items may be able to still remain in a backpack, if you are placing it on the ground. Just a little bit of an explanation as to the use of this system, because it appears that some people did not understand my meaning.

Another system that could be looked into is a weight system. You give each item a weight, and allow the character to carry only a certain amount. If the character is overburdened then they are likely to move slower and tire quickly. If they are unburdened then they are free to fight and run as they can possibly be. This is something that I have only just recently seen emerging in games.
