Each quest has multiple paths to completion, and how you choose to complete one quest can affect what quests are available later on. In addition, we have a new category of quests that we term "freeform encounters." As you travel, you'll come across these encounters all over. They're not as big as a full quest, but they will present choices, opportunities for reward, interesting sights and sounds, and more. It should be quite some time before you run out of things to do in Fallout 3, and there will always be more to hit when you play through it again.

Other quests run the gamut of possibilities that a war-ravaged wasteland offers up. For each quest, we try and provide opportunities for as wide a range of playstyles as we're able (Stealth Boy, Combat Boy, Science Boy, etc).

Providing the player with a range of moral options has been a top priority for us since we started. Players should have a variety of ways to role-play their character as evil, good or some shade of gray in between. We look at every quest in the game this way and try wherever possible to support as many different moral outcomes and playstyles as possible.​
