ok, thanks for the warning, I'll avoid that game then.
I don't have problems with seizures, but someone might look into my apartment with a telescope and I certinly don't want that person to get sick.

Browsers offer an option to block autoplay of video and audio content and disabling animated images. Both should be activated to prevent health problems for people suffering from seizures.

I'll probably only call out games that I'm aware to have caused issues or complaints.

Worth noting that, at release, Cyberpunk 2077 would actually cause seizures; one reviewer couldn't play certain (apparently mandatory for main quest completion) parts of the game because of this.

Unfortunately, they don't work as well as one might like.

Chrome/Chromium, for example, will not block autoplay on sites that you've regularly played videos from.

Also, disabling image animations seems to be one of those features that used to be common in web browsers, but seem to have disappeared over the years.

The video doesn't autoplay for me but the game description has an animated image that is like the video, with strobe effects and flashes.

It doesn't seem to be as bad as some other stuff I've seen but definitely I could imagine that it might trigger something with people sensitive to that sort of stuff.

Definitely the animated image is a bad idea out of an abundance of caution, and high frequency animated images (more than 2Hz) probably should be disallowed on Steam for the same reason. But no-one from Steam is reading this.

I don't think the game in question is so perilous to health as to warrant a warning on a different platform however. Surely there are better places to post these concerns.

In case native methods fail, which sometimes they don't, using an extension usually does the trick. For some browsers they are also the only way to stop autoplaying media.

The options are still there in Firefox' about:config and Chrome has a command line flag for it.
