Not everyone is a coomer who wants to revolve their life around sexuality.
You can acknowledge that sex exists without someone's life revolving around it. Just like "wanting sex to be private" may not mean that someone is just terrified of the topic itself or thinks all sex is gross and should be avoided.
Just because people have different values than you doesn’t make it sad.
Some values become more of a target for criticism than others. "No one should make content that I don't personally approve of" is one that I would categorize as worthy of criticism.
In this case, OP is stating that he thinks no company should be making games with any type of sexual content. Just in case his kids want to play that game.
That goes beyond "monitoring what their kids play" and that's why people are reacting strongly.
Also, you can distribute your version, of course you can.
Are you sure?
You may Distribute Engine Code (including as modified by you) in Source Code or object code to a third party who is separately licensed by us to use the same version of the Engine Code that you are Distributing.
Any public Distribution of Engine Tools (e.g., intended generally for third parties who are separately licensed by us to use the Engine Code) must take place through a marketplace operated by Epic such as the Unreal Engine Marketplace (e.g., for Distributing a Product’s modding tool or editor to end users) or through a fork of Epic’s GitHub UnrealEngine Network (e.g., for Distributing Source Code).
So, you can only distribute source to people who are specifically licensed by Epic to use the source. That sure doesn't sound anything like "open source" to me.
you can’t use most open source code “however you like” either
Alright, sure my language was overly broad. "The licensing is restrictive in a way which makes it clearly not open source." would have been a better choice.
...the main restriction with unreal engine is that you can’t mix it with copyleft licenses and you can’t use it commercially.
So, it's not open source.
...but you can do what most people want to do, modify, extend, fix, learn. that’s the most relevant thing for what we are talking about here
That still doesn't make it open source, mainly because you are missing one of biggest aspects, distribution.
keep in mind that unreal engine is also open source.
The Unreal Engine is not open source by any reasonable definition of open source. Being "source available" is not the same as open source, as you can't use the code whoever you like.
Long are the days that devs would need to write their own tools and even engines to put the game running. Some (like Naughty Dog) would even hack the hardware in order to bypass limitations of it.
Re-using engines has been around for basically as long as game development has existed. This idea of some mythical age when game development was more "pure" is a fantasy. What has changed is that expectations on AAA titles has grown to the point where it's extremely difficult to roll your own engine if you are committed to many, many years of work.
Not to mention, it certainly doesn't guarantee that the engine performs well. Look at Starfield or Baldur's Gate 3. Both have noticeable issues with performance, and both are built on in-house engines by their respective studios.
Within a system you can bring up the "scanner tool" view in the ship to then point yourself to a planet and travel that way.
But to to travel to various systems, yes you'll need to use a menu. But then I'm not sure how you would expect to fly between systems without some form of menu to select where you want to go.
