You know, I've been wondering this for a long time but doesn't the megaman franchise have a set order of events?
X series goes into Zero series, Zero series goes into ZX series then Legends happens Battle Network series goes into Starforce series
Classic series has no actual ties to either series the running theory for decades was that Wily created Zero who proceeded to slaughter the entire classic cast before being sealed away and Light built X in that period was proven wrong years ago,too
But if ZX leads to Legends then which route for both games is canon, the little ads from back in the day implied the two protagonists from both games would be working hand and hand with each other but in the game proper they never once interact and some people theorized that the other character you don't pick dies but so far there's no proof of that and finally both routes in both games end on massive cliffhangers.
Oh well, it's pointless to mull over, I'm just rambling for the sake of it because it's been bothering me for the past 30 minutes. Capcom's never gonna fix the plotholes and cliffhangers of the X to Legends chronology especially since that Mega Man 11 game didn't do so well, the next X series game is a crappy mobile title and unless they can be convinced a megaman game could do sells numbers on par with Zelda or Mario mainline titles why are content to just release collection packs like these over and over and over and over again.
Legends technically has no real connection to the other series, but one could argue that is because it takes place so far ahead in the future that humanity has forgotten all of the events that took place in the Mega Man/X/Zero/ZX timeline.
And you will never see Capcom bridge the gap between Classic and X because that means they wouldn't be able to make new Classic Mega Man games.
