When I was a kid, I used to go all over the internet in search of flash games. Back then, there was a thriving ecosystem of hundreds of sites, big and small. Creators would be sponsored by a site like armor games, or promote their own site by posting games to other flash sites. Other websites would have their own niche, like stick page only having stuck figure games, and sugar toast having joke games like Mario but you are a goomba, or Tetris 1d (there is only one row and a line piece).
Luckily a lot of these sites were big enough to stay afloat. Heck I even found out that StickPage is still up.
There are a few I do miss.
jmbt02's old site was a place I used to visit because of the
Ball Revamped games. His website seems to now be inactive and replaced by a more commerical site for his games, under the elephant mascot.
Another one I miss dearly is
egg2.com.
The website looked like this until it's death and it makes me so nostalgic, I remember being 12 and saying how cool it was that it didn't change since I first found it. I used to go to this site to play a sumo game where it's like that Mario party bumper ball minigames, robotic fishy (who's intro music I later Shazam as a teenager and add to my collection.) and a few others.
I also miss
not doppler. While technically not fully dead, it's impossible to find the old games unless you manually find the archive on your own. They understand only shifted to making steam games, but I used to come back every Thursday and I remember their cool sounding intro to this day.
Max games is in a very similar boat, still up as a mobile/steam developer but they don't even have an archive.
