Fallout: Tactics and FO:BOS are not considered canon by the fanbase and by Bethesda Softworks because of numerous controversies with previous games.
Since Fallout 3 is an "official" sequel, will it therefore have to be considered part of the canon, or if It's terribly received by the fanbase will it be overlooked when/if development starts on Fallout 4?
