It is my personal oppinion that all "spin-offs" are canon, (of course, if they were canon they wouldn't be named spin-offs), I mean, re survivor was, in my psx days when I was 14, my concept of a "RE4", the chronicles games are canon, obviously, EXCEPT for the exclusion of Barry as a survivor of RE1 unless capcom killed him in their new chronicles canon cause he doesn´t appear on the RE3 helicopter either. In wesker's report is stated that Barry survived, but it is also stated that wesker got a hold on Sherry and Dark Side chronicles had a different opinion, so Wesker report isn't canon anymore according to capcom.
The outbreak games (which I hate, being a Ps2 supporter I couldn't believe this is what I got instead of RE0 and remake) don't have a reason to not be considered non-canon either. The survivor 2 narrates the code veronica stages which are canon.
Dead aim is the one that confuses me, but it was just a bloody ship, so who give a f***, and re gaiden should be erased from the re library......it was awful

Hey! No dissing on the Gaiden! And Dead Aim was one of the best RE games.

As for Barry, he's still officially alive. Has been since the first.

Outbreaks had some details that would render them non-canon, but the timeline is a bit blurry sometimes so I too consider them to be at least somewhat canon. Confidential Report is also one of those games which is not directly linked to any of the other games.

All numbered games are canon, including CVX. The Chronicles games take precedence over any other game's canon, and by that I mean that all parts of the numbered games shown in the Chronicles games are canon as told through the Chronicles. Does that make sense? After that, only games that Capcom officially announce as canon are canon. The CG movies are also canon.

On some other thread Nite said this better but Barry not being in the Chronicles may be because it would've somehow messed with the railshooter thingy idk. Capcom is never consistent so I wouldn't worry over such matter. Barry is alive unless this is officially proven false. Capcom has just "retired" the character. The Chronicles just round some stuff.

Well, the intervening would be a big reason to drop them off from canon. Still, I too consider them canon. Something like the cameo of Nicholai could've happened. My point in saying they're "somewhat" canon is that some scenarios are true for only a given number of characters while canonically the others never where there.

Why wouldn't the mobile games be considered spin-offs? Mobile gaming is as high as ever and while others (Missions and its sequels) should be considered just minigames, Confidential Report and i-Survivor give us an actual original storyline while Genesis and Uprising retell the story of 1&2 in mobile format. There's also Degeneration which is the playable version of the movie.

I didn't say Gaiden was canon (of course it isn't, have you seen the ending?) but it was a great game. Besides, I have my theory of its ties with Revelations.

Dunno, Capcom never seemed to care much for Barry. We've only seen him as a playable character in RE5 mercs and some story in the official comics since his last major game appearance (RE3) which still was nothing more than a cameo.

I haven't played i-Survivor either (sadly) but I'm not going to buy some iWhatever to play it. It's supposedly a continuation of CR.

And yes, that's the ending I was talking about The game had no other endings but anyway. Well, if my theory proves wrong we'll propably never hear anything about Gaiden again.

In the RE canon, Barry is alive. The survivors of the mansion incident are as follows: Chris, Jill, Rebecca, Barry, and Brad. And Wesker of course. As for the Chronicles...Whenever the numbered games conflict with the Chronicles, the Chronicles have priority. Not everything from each scenario was shown in the Chronicles though. It was quite crammed together and yes, they left Barry out. Probably for time constraint reasons. Now that I think about it, the Chronicles may not take precedence. I don't know. It's just a big mix.

One thing: could you clarify which games are in your canon. A clear list or something. This just out of interest.

This is how the timeline would look with every game in it: http://www.residentevilforums.net/t1788-resident-evil-chronology-timeline#23316
That also shows how I see the canon.

Well certain things in the Chronicles are canon. Like the fact that Chris and Jill both explored the mansion instead of one of them being trapped in the lab the whole time by Wesker.
