Mass Effect Andromeda is complete trash xD Don't leave it taint your view of the OG trilogy. You don't need to play the previous games to know what's going on as the game is set 100 years after the main trilogy and there's very few call backs.
For the game itself you might enjoy it more if you haven't played the others as the big twist in the game is just a recycled idea from ME2. I hope you can find some enjoyment in the game!
Oh I see will try the Trilogy then someday down the line!
Trilogy is the bomb! Hands down it is one of my top 5 game series!
