Resident Evil always took itself seriously, which has not changed in the remakes.
I think you are right about Resident Evil series, except RE 4. I feel that game was self aware. But yeah; even with hilarious voice acting & writing, RE 1-3 was "serious".
I couldn't explain myself better at my post. At 90's, early 00's; you could have a "there is a virus, if we can't stop it it gonna fuck in the arse! Here's your guns, go !" kind of story / narrative and it would be more than enough for a game. Since 2010's though it changed. It is like game developers had a mental breakdown because their parents told them "get a real job, games are for kids!", and they decided to make "mature" games. I mean, look at Last of Us, nuGod of War, Horizon etc. . Making a fun game isn't matter anymore. Hell, even making games doesn't matter anymore; they are making movies with bad gameplay and shitty messages. (Sorry for the rant. I think I hit an age that I am constantly angry at something)
