Like, why my Shepard is grounded? Where is Normandy and the crew? What happened with Cereberus? What happened to Shepard's spectre status? How much time has passed since the ending of ME2?
I am taking a role of Shepard - my avarta seems to know what is going on, while I (as Shepard) have no idea whats happened between the ending of ME2 and the beginning of ME3 - see the problem?
Big case here.
Sheppard knows what happened in her life. Players do not. Players know what happened in certain segments of Sheppard's life.
The same thing happened at start of ME:2. Sheppard knows what happened in the six months before the jump. Players much less.
The in betweens are not storytold in the series.
The issue about time is already answered. The arrival ends on a countdown to the invasion. At the start of ME 3, the invasion has already begun, making de facto the countdown obsolete.
The other issues are not answered in the arrival dlc, they are answered in ME3.
ME2 ends on a ticking countdown to the invasion. ME3 starts days in after the invasion.
The situation calls for confusion (the ominous threat long denied and finally materialized)and players are carried to that general confusion state by being confused themselves (as an evidence of the confusion, players are confused themselves)
The narrative structure uses classical ropes. One is already used at the start of ME2: misallocation of Sheppard despite clear situation. The invasion is known, Sheppard is known as the galaxy saviour yet he is prevented from fulfilling his destiny.This leads to confusion as players are denied in their almightiness.
Another trick used is forcing players to catch up on events. Classical rope again.
Players are plunged in the aftermath of an event without knowing of the event or its implications.
The situation was written to be confusing. Playing the arrival does not remove the ropes supposed to cause confusion.
Playing the arrival does not mean knowing the aftermath of the event. Nor does it allow to make sense of it.
The complaint is about being confused at one moment writers want players to be confused. Which is another weird case of feeling unsatisfied by being given what is desired.
Another type of complaint could that the recipe to achieve confusion is overcooked.
Done too many times to achieve the purpose. Issue in this case, it demands not to be have been confused in the first place.
