Seems like the reviewers are especially harsh on Anthem
Usually the boring AAA open world games have 8 as bottom line
That's because this game is
especially boring.
It's a looter shooter with an uninspired and limited loot pool, half-assed RPG mechanics, a so-so combat loop with combo mechanics that are poorly explained, and a practically non-existent end game that relies on the strength of the loot to keep people interested (see the first point). Even if you take PVP out of the equation for a proper apples to apples comparison, vanilla Destiny 1 launched with more activities than Anthem has.
For the last few years BioWare constantly talked up how the world building and story would be a differentiating factor between Anthem and the rest of the genre. They assured us repeatedly that it would have the BioWare touch or BioWare feel.. But it just doesn't. It's hard to believe this is the studio that managed to pull off The Old Republic, putting in branching, multi-level stories for multiple classes in an MMO and the best they can do now with Anthem are binary options that have little to no impact. And the character quips themselves are just as bad as "no time to explain" or "we've woken the hive".
Destiny reviewed in the mid-70s for all platforms. Anthem has a
slightly better story (but only ever so slightly) but everything else feels inferior to what was present at vanilla Destiny launch. The scores thus far, at least IMO, feel justified.
Edit:
It's a GaaS game, reviews really won't doom it at all.
This whole thing is starting to remind me of the MMO market circa late-2000's/early-2010's when everyone was trying to take a piece of the WoW pie. Developers forgot that people only have a finite amount of time and money and players can't flock to every new game that comes out that demands all (or most) of either time or money (or both).
All these GaaS games want players to spend all of their time behind them, just like MMOs did. They want people to become invested and spent as much money on microtransactions and extra content, similar to MMOs with expansion packs. Eventually, like MMOs, the whole house of cards is going to crumble and leave only one or two major contenders and a handful of stragglers hanging on for dear life by their fingernails.
