estes conselhos parecem-me importantes, para o inicio do jogo... não sei se já foram rectificados ou não
Fatal BugsCurrently, Fallout 3 in its unpatched state has a few fatal bugs that corrupt your save files. These in turn affect the movement of the Right Analog Stick during any non-VATS gameplay, such as moving around, searching bodies, etc. This particular glitch kicks in after you die and reload from the last Autosave. To avoid this, make sure to keep several separate Save Files so you can revert to a previous save if necessary without losing much gameplay time.
When you reach the Brotherhood with Dr. Li don't teleport out before they open the gate or you will be permanently locked out of the Brotherhood and never get to finish the game!
Leaving So Soon?When you begin "Take it Back!", the final section of the main quest, DO NOT report to Sarah Lyons before you have saved and DO NOT save over that save. Once you report to her and begin the charge on the "Jefferson Memorial" with "Liberty Prime", there's no turning back. You will be unable to travel or leave the area and when you get into the "Jefferson Memorial Rotunda", the doors will lock behind you, sealing your fate. This means that unless you save before beginning your onslaught, your file is forfeit
este segundo é muito importante, gravar um save file antes de passar esta area pois não há retorno
