Hehe, I was dreading this question.
But since Im directly responsible for this, might as well come clean.
Yes we have considered it.
In fact, thats how the game was for a good while; every weapon dropped by NPCs would be fully loaded.
Early playtesters wound up with hundred of bullets in their inventory and never felt the need to scrounge for ammunition. That was around the time the game was reported to be too easy.
So we did a loot pass for the whole game, drastically reducing the amount of ammo in the game.
When our next playtest session came around, two things occurred:
1- People were bitching and moaning about the lack of ammo.
2- The fun factor went up. Drastically.
Turns out that reducing the amount of ammo in the game forced people to stop and think. People started to get what Deus Ex was about. We saw a lot more exploration and creative problem solving.
We couldve reduced the number of pickups instead so they could be full when picked up, but that wouldve meant having levels that are almost empty and bodies with hardly anything worthwhile on them.
With less and less time at our disposal, we opted to leave things as they were, deciding that having pickups with fewer bullets was the best trade-off we could make given the circumstances.
So now you know
