I'm Just wondering if this is true, As I have seen people say they consider it canon but then I looked at the FO wiki and found this "Most of the criticisms of the game came from its incompatibility with the story of the original two games, not from its gameplay and is not considered canon by Bethesda Softworks.".

Only the "high-level" events are considered canon by Beth. Due to numerous inconsistencies.

Thanks for the fast reply. Is there any chance you can give me a run down of what the "high-level" events are? Thanks.

Key Events of tactics are canon......and here is styles to say it as well and tell u about the barnaky ending haha

we don't know which events...but we assume things like the calulator etc. the reason it's not all canon is beth didn't like that it didn't have the 50's era style

Your welcome. By "high-level" Beth ( I assume) means The Midwest BoS taking on Latham and his mutants and the Reavers and the Calculator's army. Along with whatever ending Beth decides is canon.

Yup, "high-level" is just major plot points like the MWBoS's presence in Chicago, their recruitment from the populace, etc. Questionable stuff like their usage of airships is generally ignored.
