There is many hidden quests in Fallout 3 but i there is one when you reenter the vault. (after you father dies) hang around the vault entrance.
Kill people, do quests, pick locks, and hacking terminals.
No,since some quests require others to fail. However all AVAILABLE quests will keep ya playin' for a while..especially if u got the DLC's.
yes i would recommend other games such as oblivion and fallout 3
To find a replacement water chip for Vault 13.
Try loading a save you had before broken steel.
That's a difficult question to answer, as it's asking really how long a piece of string is, it depends on what quests you encounter, if exploration of the world is something you enjoy doing, etcetera.I will say that Oblivion: GoTY has had an assumed 100+ hours of gameplay time with Fallout 3 (+DLC) having something similar.Both games have short main quests, but are full of side quests, unmarked quests and places to explore of your own initiative rather than a quest taking you there.Best of luck on your purchase.
Definitely Fallout 3. Prototype is a great game, but the graphics and the length of the story line are no match for those of Fallout 3. Plus, if you have the PC version you can download tons of free mods, quests, and buy download able contents which are made by Bethesda itself! (Warning, if you don't like fps or rpg games.. Then Prototype might be a better game for you.)
Yeah that would be fun.
Yes. The 'Broken Steel' expansion for Fallout 3 continues the story from where the base game left off, and allows for a 'sandbox' ending, meaning that the player may still continue to explore the game world even after the all quests have been completed.
