It's a few things.
>1: Women started using the internet
Women don't like things, they like fitting in. They'll pretend to like things just to fit in. This is why it's long been a stereotype for them to say that something is "so last year" or even "last season."
>institutions have done their best to feminize men
More men act like women. This has consequences. See above.
>third worlders got on the internet
They don't play real games. They play quick cheap games which are likely to have far less content. Thus you'd get bored faster with them. Also, of course they can't be the most complex games, as they don't have the language skills or even IQ for that.
>games started taking way too long to develop
One dude in this thread referenced Skyrim like he's nostalgic for it. What are you talking about? That game just came out. I mean, where's Elder Scrolls VI? V is the newest one, so it must have just come out. Same with GTA V.
Oh, those games take forever to come out? You know which games don't? Quick memegames that barely have enough content or quality to hold your attention for a week.
And of course there have been other things mentioned, like social media and streaming changing how things are promoted. Distribution, too. Back in the day you might not even know about a game until it was out and you saw it on the shelf at Blockbuster or whatever. Maybe it was out for a while, and your buddy told you about it. Popularity might be more of a slow burn. It took time for info to disseminate. Now people are "hyped" years before a game releases. Then it releases and it's shit, so everyone forgets about it, but for that one day when it first game out, their "hype" paid off.
