That's not the argument being made here.
The argument the author is suggesting is that Andromeda doesn't stand out in 2017. There are 2 fantastic open world games that just came out in the last month alone. Why should anyone waste their time playing Andromeda when there are much better open world RPGs out there right now?
Also, open worlds in games have only become a huge trend in this generation. Last gen we only really saw Skyrim and the GTA series.
This year has had a crazy number of good titles. Yakuza 0, Resident Evil 7, Tales of Berseria, Nioh, Horizon: Zero Dawn, Zelda: Breath of the Wild and Nier Automata have all come out in 2017 alone. I personally don't see any reason to choose this game when there are much better alternatives out there. Hell, Andromeda isn't even being made by Bioware's B team. It's supposedly made by their C team. So it isn't even the same development team that made the past titles.
I feel for the Mass Effect fans though. Unfortunately it doesn't seem like they're getting the game they deserve.
EDIT: I should have corrected myself to say "I think the argument the author is suggesting" instead of "that isn't what the author is arguing." My bad. Also, I agree with Fox's post.
