Things from back in the day that are disappearing or have disappeared:
*"Arcade-style" OSTs. Think Castlevania, Contra, Streets of Rage, Sonic, Super Mario, etc.. Nowadays, it seems like every big AAA game has mostly atmospheric music. While this is fine (and even preferable in some cases like with survival-horror games), it also makes me wish I could have music playing in the game that makes me bop my head and look forward to coming to a new area. Bloodstained, being a Not-Castlevania game, did this for me, even if the music itself just didn't quite reach the highs of Castlevania at its best IMO. The Yakuza games also have mostly this high energy OST style as well.
*Here's where it could get...controversial. Being able to go into a game without having wonder if the game has been tampered with. It kind of crosses over with my first point in this category, but this has more to do with trends in developers trying to throw politics into your face when the game in question doesn't really revolve around it. For example, if the RE2Make had some BS about making the police chief a gun-loving monster who says that he's gonna Make Raccoon City Great Again as some sort of subtle jab at conservatives, it would be dumb considering that it's a game who's story is set in 1998 and here you have a police chief that references a slogan that was made 16 years after the fact and would ruin the period piece that the remake was. Outside of some twists and turns, the RE series' plot revolves around characters trying to survive situations caused by corrupt corporations that have had parts in various events in the series. It's never been anything dumb like, "This is why we need to overthrow the burgeouise and let the government do this or that." If anything, if the masterpiece of a game that is Resident Evil 6 is anything to go by, corporations are often in bed with government officials and really, corruption is to blame. In comparison, that's a theme that's more universal and transcends all of the identity political BS that goes around these days. Like, I get that people feel like they're disadvantaged about this or that because they're X and/or Y thing, but just because we get a hypothetical game where we get to play as Marvin Branagh (RIP his role in RE 1.5) surviving the events of RE2 just because "muh diversity" doesn't speak to anybody on any level deeper than the surface. The game came out the way it did in 1998 due to a lot of issues in development and Marvin Branagh being subject to dying first in Leon's scenario (which might not even be technically accurate if you consider LeonB as opposed to Leon [2nd] and that Mike Haggar-look-a-like) had more to do with writing decisions that came about when the devs at Capcom decided to bring a more professional writer to help salvage the mess that, to sum up what Kamiya and Mikami said about RE 1.5, wasn't worth following through to a finished project (laboratory aside, because if you've played the MZD build, it's essentially the same area as in the final game, but with some different layouts, designs, and a couple of extra rooms pertaining to how some people theorize RE1.5 would have played out based on what they pieced together). It's not some conspiracy by some evil white supremacists that they decided to off Marvin the way he did just so you can accuse some game of being whatever -ist/-ism you can try to form something masquerading as an argument.
The fact that I have to do a write-up about the above just goes to show how bad it's got with some games and the content being brought over here. Many have said the player deaths (as in, when you get your face smashed in by Mr. X) looked like they were censored the way they were handled, and hey, it wouldn't surprise me. Some of the deaths in the original Resident Evil 2 may not look like much on the PS1, but can you imagine some of that shit in RE2Make had they not wussed out because Japan, ironically enough, is more sensitive about violence and more steamy content being shown in games not the equivalent of AO nowadays compared to the 80's and 90's? And it's not just Resident Evil. Catherine, with the Full Body remake, from what I understand (this is where I would need some context as I never played the original and traded in my PS4 Slim the other day and some other stuff so I could get the Switch with the drastically longer battery life), a new romantic path was added where a woman who transitions to a man is convinced out of it, some time travel occurs (or something?), and they're still a woman sexually and...genderly. (hey, it's a word on Urban Dictionary, at least!) If the story had ended there, and the game's original vision was left intact for the US localization, that would have been fine with me. After all, if you are against censorship of violence, profanity, and everything else that's already going down a slippery slope to 1984's Ingsoc in America, then you should be all for someone across from the world saying whatever they want, right? (you know, as long as it doesn't incite violence, which I'm pretty confident this game wasn't doing) But then, REEEEEEEEsetERA had to stick their nose into business involving a game they were never gonna buy in the first place. Ultimately, just the wording of some conversations was changed from what I've read that mean the same thing.
I guess I could just ignore all of this and not type out the two paragraphs above. After all, ignorance is bliss, right? Unfortunately, my time is limited these days, and playing video games isn't as high on my priority list as paying off my student loans and then moving out after that so I can finally be truly free in my personal life when I'm not working. Maybe, when I can do that, when I achieve more goals in real life, I might sit down and start playing some more games as opposed to right now. If I can find a reason to not have to buy a game and either save that money here or there, or to do this or that, you better damn well believe I will do that, especially considering how much time I spend at my job every week feeling like I am doing the same thing over and over again.
But, anyways, as for things that will stay from the modern gaming industry, well...
*Microtransactions. Call them surprise mechanics, call it horse armor, call it scamming, at this point, this is something that's here to stay, government legislation by the EU notwithstanding. This and its sibling DLC are going to be around as long as people keep buying season passes that make games cost twice or triple the amount when you bring multiple season passes into the picture. You can complain all you want, but it's not going away anytime soon based on the people I see at retail!
*Services becoming a bigger part of gaming whether we like it or not. If anything, I'm surprised that it took Street Fighter 5 as long as it did to become FTP given how much of both of the above it has. I can just see, in a future where streaming somehow becomes practical where you have multiple fighting game services competing with each other. You have the Street Fighter service, the Guilty Gear service, the Mortal Kombat service, the Tekken service, all being monthly payments you opt into or you don't get to play the newest, constantly updated version of all of these games that have sequel numbers that Halloween and Friday the 13th wishes they had!
