Unity (former game engine company) has merged with an actual adware and malware distribution company. That's not an exaggeration. Fake Flash installers, was blacklisted by Microsoft's anti-malware tool, VirusTotal entires, that kind of thing.

Don't build your games on engines you don't have the source code to.

Adware Empire - IronSource and InstallCore

A recent Adware campaign using malicious Bing ads led me to a Chrome download that eventually deployed Adware to the user’s computer. The IPs and types of Adware connected back to IronSource Ltd., Babylon Software Ltd., and InstallCore – all Israeli companies that have connections to Adware. See her

INFOSTRUCTION
... if you can avoid it. Pico-8, GameMaker (though they're on some crappy subscription thing now), etc. are all OK for making smaller games. If you're going to invest many months or years of your life into some long-running project, maybe consider Unreal or Godot, instead.
@cancel I tried Unreal recently and the install size was so massive I had to uninstall it. Over 100GB for Unreal 5, and that's with no platforms or add-ons.
@calutron I mean, it's going to be big. But I thought it was like 35gb with just the base stuff? Are you sure you didn't opt for a bunch of extras? (Are you on Linux?)
@cancel Mac. 35 GB is the size of the....like the bundle you download? But when the process is over, it's over 100 GB. I've seen the tips about extra stuff, but the recent installer for the recent version doesn't even have that as an option. It just downloads as an un-editable chunk.
@calutron It's probably downloading both the Intel and ARM versions, *and* the debug info for both. (The Mac and Linux debug info formats are somewhat space inefficient when compared to Windows .pdb debug info files.)
@cancel Ah interesting. Maybe there's a way to then remove that extra stuff. Hmm.
@calutron You probably need to uncheck debug symbols, uncheck the platforms you don't need, etc., then run the cleanup thing (does that exist?) so it prunes out the stuff it doesn't need.
@calutron Debug symbols are usually the largest part of the engine binaries. They're usually 20x-500x the size of the app code itself.
@cancel The 5.0.1 install has this "options" dropdown where you can uncheck things but 5.0.2 does not
@cancel sorry if I'm missing something obvious
@calutron I don't know, I haven't used it in a few years.
@cancel Ah ok it's a bummer because I don't code really and Blueprints looks great
@cancel I tried again just for fun. Same result. Oh well!
