While I'll always perk up when I hear the mention of "more Mass Effect," the cynic in me overwhelmingly thinks this is feathery bullshit they're putting out there just to make us feel better about Anthem.
Facts are, Anthem basically exists at the expense of the Mass Effect series. It's what put their "C" team on it and the amount of "care" shown to such a beloved series was damning. Everything about the production/release of it shows what a shitshow it was, and even though it still sold millions of copies, they unceremoniously cancelled obvious DLC and support for the game. Seeing Mass Effect skins and whatnot in the game that basically exists at the expense of that series is just rubbing salt in the wound.
Anthem is a game that if it goes well enough, will never be "done." "After" Anthem, they still have the next Dragon Age, which sounds like it is in its infancy of development...AND THEN, maybe Mass Effect? Like seriously, if things go well, can we expect that in 2026 or something?
So yeah, their track record is shit. The huge demand for a remaster of the series seemingly fell on deaf ears (and their idiotic "no remasters" mantra ended up being bullshit as they released Burnout, which was excellent!). The myriad of ways they catastrophically bungled Mass Effect as a series and how they treated Andromeda just shows that their actions speak louder than words.
I wish video games were like sports and they could trade the Mass Effect series to someone else because I'm honestly not confident at all that they'd want to create the type of game anymore that die-hard Mass Effect fans would even want.
