Need help deciding on mass effect.

Let me clarify: I played bioware games before (DA series) on pcand just wanted to know if I would be lost lore wise on ME: Andromeda.

A no brainer. The first in particular is better on PC.

I really doubt you'd be lost lore-wise if you didn't play the Trilogy before starting Andromeda.  Bioware will no doubt fill in the Codex with anything really important for you to know.  There is also a series of books planned for those who want to delve deeper into the story than what will be just provided in the game.

I'd just suggest playing Andromeda first and then playing trilogy if you like it. Andromeda is basically a reboot far in the future, far away from the same galaxy that ME 1-3 took place in. None of your saved games will transfer to Andromeda. Andromeda is designed to be a jumping on point for new players so don't feel obligated to play the trilogy for the backstory.

I do agree with the DAI analogy -- why start there when you can go back to Origins and see how it all began? Each game is still building on the previous game with saves and world states carrying forward. It's all connected. With Andromeda, it's a clean break.

I absolutely love the Mass Effect series. I love Mass Effect 1 and adore the Mako. I even enjoy the jenky gameplay (except against the Asari Commando Unit). The entire trilogy is well worth the money and time put into it. I've played through the entire trilogy at least 6 times, probably more, and put over 400 hours into the multiplayer (small potatoes compared to many of the veterans, but still shows how much I enjoyed it). The story is fantastic, the DLC well worth it. I didn't even hate the ME3 endings as some others apparently have. I actually found them very fitting. But even for those who disliked them, I think many would agree that the other 100 hours of single player story and replay-ability are well worth it. Honestly, it's the best game series I have ever played, and has had a tremendous impact in my life.

I don't think you'll find anyone here, telling you not to play the original trilogy.
Even people who are still salty about ME3's ending (like me) will tell you to play all three. (Also, it's not like there are too many options out there for Sci-Fi RPGs.)

As to whether you need to play (or read?) anything before picking up MEA, I think the answer is no, as many others have already stated; that's because this is pretty much a reboot.
