[quote name='Ryuukishi']From best to worst:
1. Lair of the Shadow Broker (best DLC ever, high point of the entire game/series)
2. Stolen Memory (really love this mission, Kasumi is a great squadmate)
3. Leviathan (great gameplay variety, similar to Stolen Memory)
4. The Price of Revenge (mission itself is nothing special but Zaeed is one of my favorite squadmates)
5. From Ashes (similar to Zaeed, so-so mission but awesome squadmate added)
6. Overlord (fun but nothing special, just a slightly beefed-up ME2 sidequest)
7. Bring Down the Sky (meh... unmemorable)
8. Arrival (very meh... hated playing without squadmates)
9. Pinnacle Station (awful, completely misses the point of Mass Effect)
10. Firewalker (so awful I never even finished it)[/QUOTE]
My list:
1. Lair of the Shadow Broker (great combat, Liara, significant plot resolution)
2. Bring Down The Sky (I also liked the combat, Mako parts, variations of the end with Kate/Balak)
3. Overlord (fantastic ending sequence, very cool atmposphere)
4. Cerberus Network DLC (almost entirely because of the Normandy Crash Site sequence)
5. From Ashes (Javik was a great squaddie in ME3, setting aside the day 1 DLC mess)
6. Stolen Memory (introduced great SMG, Kasumi)
7. Arrival (would be higher if you could have brought squadmates)
8. Firewalker (worse than the Mako!)
Never played Pinnacle Station and I havent got Leviathan.
