I would have to look at it again, but from what I remember it's for the base games and any dlc included with the base games only.
Thanks. How much should I expect to pay for the DLC for all three games?
It's better not to get all DLC. It would cost you $80+. Easily.
I've been thinking about the ME DLC and researching it for some time now.
And it's best to not buy any for ME1 (one is free, the other is not worth it because it's combat-centric)
ME2 - the worth ones are definitely Shadow Broker, Overlord, and supposedly Kasumi too (1920 bioware points)
ME3.- From Ashes, Citadel, Leviathan (2800 bioware points)
All in all, 4720 points which is 1600 ($20) + 1600 ($20) + 1600 ($20) = $60.
The largest pack of bioware points is 1600, so that's why I wrote it this way.
I've also read that the promos on BW points are extremely rare, but I hope there will be one soon. I really do.
