Yeah you gotta put in some work for that one. Just doing those missions isn’t even enough. There’s a bunch of stuff you have to have done, some going back to ME2:
You destroyed the Geth heretics.
Tali was proven innocent in her loyalty mission without need of evidence, and became an admiral.
You broke up Tali and Legion’s argument with either a paragon or renegade persuation
You did the mission to save the Quarian Admiral, and saved his life (don’t think saving his life is MANDATORY, but it helps)
Legion has to be present on Rannoch (meaning you activated him in ME2)
Peace between the Geth and Quarian’s is the hardest thing to achieve in Mass Effect. After how that played out with two games worth of so many decisions figured into how that scenario played out, I couldn’t even imagine how much depth would be in the finale
