it's annoying that EA hides so much great content behind DLCs, those three really do greatly add to the story. If you do go back to it, have fun!
Yeah, I think EA's greed really did a disservice to the game and, therefore, the fans. It was almost a lesson in how not to treat a story driven RPG, especially the final installment of one of the most loved series of all time.
The ending, as much as it was hated, made a bit more sense and had some groundwork laid down for it with the Leviathan DLC. I think of all the DLC's, this one was the most important to have in the game on release but it really did need them all.
The Citadel DLC made up somewhat for the lack of interaction with some of the series characters that aren't in your party during the game, something that was exacerbated by the abrupt ending with no real epilogue for anyone.
After hearing so much about the Protheans, it was a also a bit nasty for them to have squadmate Javik behind a day one paywall too.
Iirc, the guns made quite a difference to the feel and flow of combat and weren't some of those DLC too? Smh.
I remember how well received, and how much I myself loved, Lair of the Shadowbroker. I also remember them saying that the DLCs for ME2 were a great way to judge what people might want in ME3. What happened to that development plan I wonder?
