Lets see, I was buying some games that are over 7 years old and that includes the old Fallout games before 2014, the old Elder Scrolls games, and then thought, "Hmm, maybe I should try MAss Effect I guess." Also because the Mass Effect game was on sale including the Legendary edition. I played Andromeda first since I have actually known a bit more about the 3 games than the Andromeda. So played that(took me 70 hours) and am currently playing Legendary Edition. I am on the third game now and getting close. Might finish it today or tomorrow.
I really enjoyed the games. My list of favorites from least to best is ME1, ME2, ME:A, an ME3 so far. To be able to experience is better than watching it from a lets player.
