Fallout 3 gave you a nice big house early in the game, with many lockers to sort your stuff - this is a huge motivator for the OCD component that makes RPGs so much fun. Deus Ex has no containers you can put anything in. You can loot people you incapacitate and there are drawers and cabinets, but in all cases its a one way trip from their inventory to yours.
As a result, I'm sorting my loot on the floor of my apartment. Guns and ammo on the landing stacked by ammo type, grenades in the bedroom, food and meds in the kitchen, weapon upgrades in the living room, and cardboard boxes (useless) in the front hall. And though there is a well-thought out method to grab boxes and carefully move them around (for getting to secret places), you can't pick up any equipment and move it around simply. To manage your equipment you have to pick it up, walk to the destination, go into your inventory menu, and then drop it. And sometimes stuff rolls for a while.
For an RPG to handle loot and equipment so crudely really pours sand into the oil. Why even give you an apartment, especially one with a secret compartment, and not let you live in it?
An RPG is not just character development, its also loot development.
