Its more on how the writing for the game is. The last few games have had generally bad writing and sometimes decent. Problem is they expect us to enjoy the story but its absolutely shoddily written. I personally enjoyed ME1 a lot more than the next two games as it also was better written and tried to follow the rules the setting established for it self. The other two not so much.
So if its well/decently written then i will enjoy it. If its trash but still forces me to care then im not interested example the brat in start of me3 sad music feel sad idiocy.
So yeah its all about the writing and it something they lack quality in. A story can be simple or even similar to another tale, what matters is how it is told. Bio in their quest to prove they can be different actually make it worse. The studio has the resources from money tech etc but they lack writing to pull it all together. One can have the resources but not the skill and this can be rectified by getting the skill hire better writers who know how to write and not terrible comic book crap.
Finally i also have to see if their writers collaborate with their cinematics department. Mass effect suffered badly from lack of collaboration where the cinematics contradicted the established rules of the setting itself. It was terrible.
If the game addresses these issues i will very much enjoy it but i fear bio is not interested in proper groundwork laying, exposition, establishing rules and following it.
In short I HOPE ITS A PROPER RPG with the work put in. But going by history the game will start of with a giant explosion/action from the get go DA2, ME2, ME3, DAI.
