Mass Effect: Legendary Edition's take on Mass Effect 3 might be a little confusing for returning players who expect lots of moving parts, but it's actually been simplified. So BioWare has changed the Galaxy at War system significantly, deleting the part that was tied to multiplayer and changing the math a bit to determine your overall military strength. But that was way back in 2013 multiplayer isn't part of Legendary Edition, and the apps and other outside elements are no longer a part of the game. When it was first released, Mass Effect 3 took into account actions you made in both its multiplayer mode and in mobile apps, which affected the strength of the army you raise to battle the Reapers in the single-player campaign. It all culminates in Mass Effect 3, where everything you do in Mass Effect 1 and 2 matters greatly to what happens at the end of the game, thanks to a change to the Mass Effect 3's Galaxy at War and Galactic Readiness system. The three original Mass Effect games influenced each other as part of one long, expansive story, and that is most true with Mass Effect: Legendary Edition, as BioWare has implemented changes that make your choices matter even more between games.
