I think I've decided to get ulitmate game pass.
It will allow me free games from their library and multiplayer mode also.
I believe it's also available on PC, but the Mass Effect Trilogy is incredible. You can buy it as a 3-game package. 3rd-person, cover-based, space shooter. You can sink over 100 hours into each game.
1st game has some clunky mechanics, and is more RPG-heavy than the rest. Story is best of the three. 2nd has MUCH more refined shooting/moving mechanics, with dumbed-down RPG elements. Story is still good, if a bit less involved than the first. 3rd builds on the second and wraps everything up. Ending was controversial, but the game, overall is incredible.
Cannot recommend the ME series enough. A personal favorite.
Witcher is also excellent.
I like Division, but that's 3rd-person shooter. Destiny is good, but I'm burned out on it. I think you can play through the beginning for free, though.
