the centuries of Maverick Wars before Eurasia
Actually, the Reploid War mentioned is the fight against Repliforce. Which makes it all the weirder.
however there is one exception to the rule if you account for terminology changes. It is exceedingly rare, although possible, for a change in terms to impact story events. This happened in Legends 2. Instead of Barrel enjoying a pun-name for his mysterious baby, we're left to ponder what powers of persuasion Roll had at less than one year of age.
In the MegaMan universe, Mega is a perfectly fine pun on Roll! >.>
If you follow Zan's logic you might wanna seperate out the MM1 manual from itself, or group it box stories. I don't, but I leave it to you.
I think games, manuals, sourcebooks and such should not be separated.
Hence, the MM1 manual goes wherever the things I previously listed go. That is; the list of things that slipped in during the localization process, whether it be included in the manuals or games. So, the Wily is assistant notion goes in the same term as "Die Wily!" and such. Said term being either "US canon", "localization oddities," etc.
Is the Radio drama part of Japanese game continuity proper? If not, it goes on the list.
Not sure if that one is Capcom produced , but even if it was, I think its timeline placement is too unclear to count immediately. Being after R6 but disregarding R7 elements.
Anyway, there are certainly a few stories that are of peculiar "semi-canon" status in regard to the games. MegaMission1 for instance is accepted by R20 and had Inafune's design involvement. However, its sequels MegaMission2 and 3 are outright invalidated by X5 and had no such acceptance from Capcom. (Other than say, Capcom artists drawing the art for the model kits.)
Likewise, Challenger from the Future is also mentioned in R20 (using Sprites Inc's rips no less!), but has a distinctly contradictory date of 200X for a 20XX game.
hope I didn't miss anything.
Taking a closer look at your listing...
Under MegaManX:
-MegaMission1 to MegaMission3
-Ariga's MegaMission manga.
And under classic, Ariga's Rockman MegaMix and Ariga's Rockman Remix are two distinctly different canons.
Also, you might want to account for both EXE and ZERO's appearence in Onimusha Blade Warriors.
