I have yet to have anyone properly explain how this Fallout game background setup is any more restrictive than Fallout 3 was, Frankly, the backstory of both is fairly set in stone prior to your input (or you have little choice in the outcome despite your input).
If the comparison is to the backstory / start of Elder Scroll games, I don't accept that as a fair comparison just because they were developed using similar tools, gameplay mechanics and development houses. Since when can't an author take license to use differing story devices in different franchises? The idea to me that Bethesda can't use different story development methods in Fallout than they do in Elder Scroll games is laughable to me.
While I fully understand how fans (taken from the word FANATIC, btw) have a vested belief that these games are THEIRS, it is not, and MANY need to take a HUGE step back and realize a few facts about THEIR favorite game franchises:
1) You as a player do not own the game or any characters in the game.
2) Bethesda develops the game as a form of entertainment for anyone willing to pay to participate.
2) You participate in the game as a form of entertainment. Nothing you pay for EVER implies ownership of any assets sans the media the game may be distributed on.
3) You have no rights to generate any part of the entertainment nor make any decisions on how the entertainment is written, produced or distributed.
4) You have EVERY right to not pay to participate in the entertainment when it is made available.
5) You have every right to determine if you were sufficiently entertained by the game.
Go look up the word FANATIC and you can quickly see where the disconnect between the above facts and what most gamers FEEL about a franchise exists. Bethesda have given most of here hundreds (if not thousands) of hours of entertainment so how about we give them the benefit of the doubt for now. You are certainly welcome to voice your opinion on how restrictive you felt the backstory was once you actually get a chance to play the game.
