Yeah, exposition overload is a rookie mistake a lot of writers make.
And video game writers in particular? Sometimes it feels like just having a Wattpad account could put you in top 50% of them. I've seen AAAs where saying the writing was "fanfic tier" would be an insult to fanfics. Like they either hire the cheapest people they can get, or give the job to someone like an executive's daughter with big ideas and no ability to execute on them.
A good writer knows the power of "show don't tell", and knows the value of keeping the audience hungry and wanting for more.
But to be honest, isn't this also true of the basic Hollywood or Netflix fare?.
I've been watching season 5 of Stranger Things. It has a budget of approximately 1 gazillion dollars. The writing is utterly basic predictable, boring, cliché, it's either a marvel-tier quip or a hollywood trope. Most Netflix shovelware isn't better than this.
So I don't think it's unique to video games :)
