There is a say on my country: "nem 8 nem 80" in English maybe i can translate like everything or nothing at all. Its the closest maybe
Are you saying the core of Mass Effect are the hardcore fans? same to Starwars or Star trek? (i know what the hardcore ST fans say about the new Star Trek)
Marketing is always directed to the general audience i think.
I don t like to be hardcore about anything (yeah yeah don t think about that), or fanatic.
The reason is never there.
Marketing is directed towards the general public because it's assumed the core fans are going to see it anyway regardless. Same as with the game, you don't need to market ME:A towards us because we're already interested. That doesn't mean that you should ignore the core fans, though.
I don't say core fans to mean the ones that obsess over the thing but rather the ones with more than a passing interest in it. Pretty much anybody posting on these forums I would call a core Mass Effect fan(unless they're posting just to talk about how much they don't like the game in which case I'm confused as to why they're here).
I'm not saying it's impossible to make a Mass Effect for the general public and do well with it. I'm just saying if they were going to make a TV show or movie, they'd run a lower risk by not alienating the core fans of the games.
Since the general public mostly doesn't even know who Shep is, including them on screen is basically just fanservice anyway. It wouldn't do to have fanservice that annoys your core fans. You can include other known characters from the universe as fanservice without having to turn anything canon. Even squadmates could be included, depending on the time frame of the show/movie.
