So we have two games from Fallout series beside Fallout 1 and Fallout 2 (and of course Fallout 3) - Fallout: Tactics and one console game. I have heard somewhere that F:T and this console one are not lore friendly with main chapters. That was mostly because other companies were producing those games. So I have question to you guys - I want to know if those other games are lore-friendly with main Fallout games or to skip them?...

Of the 'other' two the console one I would say is completely non-cannon and a total pile of effluent.
Tactics while it does a slightly better job of staying in-cannon still makes significant departures from what is considered to be the main fallout cannon.
From what I've seen in game there are definate references to Fallout, Fallout 2 and possible references to Tactics.

I hope this helps a bit and I haven't misread your question.

Your answer is really helpful. I am guy who always want to complete every game in series but I do not have console in my house (only PC) and was worried that I will not complete whole Fallout series. But I have heard somewhere that this console game as well as Tactics aren't lore-friendly so I wanted to have confirmation on forums. So thanx for answer.

The only people that say Tactics is not "Lore Friendly" are the idiot role players that felt slighted because it wasn't a role playing game. It is a Squad based tactical game, and it perhaps is one of the best in the genre, these are the same type of nerds that argue about Star Trek episodes.. don't listen to them.

There is nothing blantantly out of canon with Tactics. Don't listen to the taped up glasses nerds that would tell you not to play it.

Many of the desceprencies with the BOS could easily be explained by differences of opinion and generational loss of memories.
Do you know exactly where your great great grandparents are from? Perhaps some of the people in the BOS don't remember or ever knew where they actually came from. Many traditions get passed down in cultures where the people have no clue why they are used but they do them anyway.

And I have already talked about the deathclaws in 2 other threads, so I am not gunna talk about them anymore. There is nothing out of canon with them.

A few things I wish that would have been finished in Tactics are..
#1 More shops/secret places to use your ring pulls for supplies.
#2 Allowing players to use vehicles in any scenario not just the one you find the vehicle in.
#3 More gambling/whoring
#4 Allowing you to use something then your starting hero as the squad leader

Except the BOS has a clear written history and written traditions. You can even see it for yourself in FO3 on a terminal.

Fallout Tactics is semi canon, while Fallout Tactics Brotherhood of Steel is entirely non cannon. And this is the official word, by Chris Taylor and Emil Pag.

Also, this is the whole story by Ausir:

It seems that Tactics has been retconned into proper continuity by Fallout 3. You can ask for a detailed history of the Brotherhood of Steel from the Scribes in the Citadel, and they mention a "Midwestern" BOS in Chicago. If you press them on it, they say, "it's a long story."

They could be referring to Van Buren?

It was set in the Mid West after all...

Van Buren was set in the Southwest (Utah, Arizona, New Mexico and Colorado), not the Midwest. Jameson and Rothchild explicitly refer to the rogue BoS detachment in Chicago, which appears in Tactics.

Yes, Rothchild is most certainly talking about what happens in Tactics, although I really see no reason why the events that were supposed to have occured in Van Buren, and the associated lore, couldn't still be valid. Nothing in Fallout 3 counters it, and nothing in the Van Buren design documentation doesn't fit into the established Fallout universe.

Tactics is considered to be "semi-cannon" In that the events happened, but any aspect of the game that goes against things established by F1 and F2 are to be ignored. Like the talking Death Claws. There was only 1 group, those in Vault 13, and they all died. The one in Tactics are considered to just not exist.

The console only game is considered to never have happened and showed be erased from actual history.
