Just wanted to make a case for playing of me2-3dlc
some dlc have decent carry forward from 2-3
in 2 you get zaeed free.
you also get firewalker but its not amazing/critical.
Highest priority / absolute must play
Lair of the Shadow Broker -fantastic setting and battles/ large carry over into 3.
For extra squad mates , you want kasumi stolen memory
Citadel - arguably should have been in the base game. Set pre ending fantastic cap on the series as a whole. some great set pieces and combat. any fan of the series will want to see you play this.
from ashes (normally free on anything but standard edition) for javik squadmate.
Omega (excellent and challenging combat design. worth it to get an idea about the combat in Andromeda, manveer heir did the combat design for it and he has strong hand on Andromeda. )
potentially interesting plot reveals, but nothing spectacular.
Last thing i would say, ask gassymexican for his advice as a ME fan he will probably say that you cant skip shadowbroker and citadel.
