This is one of the best trilogies of all time. Spanning three games, Mass Effect provides an epic space-faring adventure to take down the Reapers, an ancient alien race that's bent on destroying all life in the universe.
As Commander Shepard, you'll recruit many different characters throughout the three games, and you'll come to love each and every one of them. Even starting from the first game, the choices you make have ramifications on playthroughs of Mass Effect 2 and 3.
The game has been approved through each subsequent title, and the cast of characters remain solid throughout. Luckily, all three titles are playable via backwards compatibility on modern Xbox consoles. Additionally, a remaster of the trilogy, called Mass Effect Legendary Edition, is scheduled to release in 2021.
If you don't want to wait, the trilogy was also made available to Xbox Game Pass subscribers recently through Microsoft's partnership with EA Play.
