I am gonna keep it simple to theee main complaints
1.As many already said the whole main story of it couldve been summarized in a single comic since all thw flashbacks from the doors are pretty short and honestly not that interesting
2.the infighting at the end really bothers me,i know the whole point is about how people react illogically if their mourning and griefing..but the thing is...THE WHOLE MAIN GAME IS ABOUT THAT,in the main game there were multiple times when the squad lost someone and had to "get over it"quickly and everyones arc is about managing grief,also the time limit excuse is silly,in the main game they had the choice to bend over to a god....or FIGHT A GOD and they chose TO FIGHT A GOD,in the main game they also have multiple moments were they all agree that changing the past doesnt matter,so the switch up makes no sense for me and no the FES version all be it has better writing still doesnt explain it well
3.The gameplay of the final fight,for one its difficult for the sake of being difficult,but what pisses me off the most is that they had a ticket for a really cool system,you as the player should be able to choose who to side with and then fight + it wouldve been cool if they were the same level and build that you made them(i know this could be exploited but still) and it just..isnt fun the entire time,if you donr have armageddon your onky two options are spamming items to win or changing to peaceful difficulty
overall my main issue is that the wholw thing feels forced,the story is acctually okay...but as a dlc its really dissapointing and honestly feels like bit if an cash grab
