Fallout 3: Power Armor, Nudity, and Vegetation

Three separate articles focusing on different aspects of Fallout 3 have hit the web - one at Destructoid where lead designer Emil Pagliarulo discusses the creation of power armor, and two at Twenty Sided dealing with an analysis of player-made risqué mods and the strange but popular "Green World" mod. Since Destructoid's article has some developer commentary, we'll quote that:
The Brotherhood of Steel armor says a lot about Fallout 3. Lead designer Emil Pagliarulo gave me his input, pegging they Brotherhood member's aggressiveness as the reason for the plating and the environment for its construction.

(You know, I think in a post-apocalyptic game like Fallout 3, when you put on a suit of Power Armor, you're saying to the Wasteland, saying to the world, '˜I'm a badass. Bring it.' These are the guys who have gone beyond survival. They're no longer on the defensive, and are bringing the fight to the enemy. Because, when you think about it, so much of the equipment used by the guys in Fallout 3 is pure crap. The guns have decades-old tape on the stocks, everything is near broken, lots of stuff is cobbled together from spare parts. Everyone is barely surviving. But the Power Armor is constructed, and maintained. It's a step above what any average Wasteland dweller has. And having access to equipment like means you're probably part of an organized group, like the Brotherhood of Steel or Enclave -- those are the guys with the resources and determination to strap themselves into Power Armor and go on the offensive.)

The Power Armor presented a few problems for Bethesda in the early design stages. The human character models aren't hulking monstrosities. The armor needed to be large, but not large enough to interfere with animations or the mix-and match nature of the accessory system. It also needed to look cool. Bethesda took great care in creating the iconic armor of the game.
