Like most, I miss a lot of the old flash games, the ones owned by networks such as cartoon network, looney tunes, polly pocket, etc, in particular... in fact, I just checked, and two of my favourite games that I do recall to this day, are available on flashpoint: witch's brew and courage the cowardly dog creep TV. I definitely reccomend both; the latter one is a point and click adventure game with great graphics, that honestly could have been a short gameboy advance game. The first one is a potion mixing game, where you get letters from clients requesting a potion, and then you have to look at your igredients' descriptions and figure out what to add. Without even knowing how many ingredients a potion has, it is very difficult, but rewarding.
Other than gaming sites, I also miss quizzilla for the stupid multiple choice stories they had where you could pretty much pick what you would and who'd you end up with. Was the only thing I liked to read besides fanfiction back then, even if, yes, most of the stories were cringe. I still got a few of my favourites saved in word documents though, years before the site went offline, an amazing strike of luck. Quotev sorta fills this hole, but the stories are even worse now and focus on boy bands, so...
Back to gaming, but keeping on the topic of stories, I miss the old Sims 1 and 2 sites. Both games had a function where you could take pictures and add text, then upload it as a story to the official site. It made finding that sort of content so much easier, and let's just say, the jokes the community used to make back then would get them eaten alive in the current TS4 climate. Things were fun back then, but now, the closest thing to those stories is cringe videos with the most annoying high pitched voices and spending a ridiculous amount of time even creating a sim. And, of course, no 'edgy' jokes allowed. Soul draining.
That reminds me, I should backup my favourites of those too, just in case the archive site for TS2 ever goes down...
Also, just how the internet used to be before the social media take over. It all feels so washed out and bland as everyone is too afraid to get cancelled and doxxed, the overwhelming desire to get attention by any means possible, and everything feels like a dang ad. The innocent times of people arguing on a random forum over who would win in a fight, Superman or Goku, are long, long gone. Finding a gaming video without someone's stupid face/vtuber avatar slapped in the corner, which adds NOTHING to the video, is like finding a gold straw in a hay field. It sucks.
