Mass Effect on Switch.
Or
Mass Effect Andromeda 2 where there's new characters and stuff where it's either a sequel, happens at the same time as the ryder story, or happens before the Ryders arrive (albeit that one might be really uninteresting). Reuse none of the previous cast except for cameos and/or certain planet quests and give new life to the Andromeda Galaxy since they botched it so ridiculously the first go around. Keep the gameplay mechanics mostly the same, fix all the terrible UI and bottom tier design decisions regarding loadout swaps and skill builds, and bring back the dialogue choices and meaningful character builder from ME and DA:I, including other races to choose.
Say what you want about DA:I, at least your choices gave you some damn agency in the game.
