What does the launcher do with regard to the operation of the game that cannot be done within the actual game itself? Is it due to a technical limitation or simply there for the convenience of the players? Are there alternatives to such methods of starting the execution of games?
Sometimes updates require a game to be restarted. With a launcher it never needs to REstart, it will be started fresh afterwards anyway.
I’ve noticed Genshin Impact on Android (which doesn’t have a launcher) regularly needs to restart after updates, while the Windows version (which does have a launcher) never requires in-game updates nor restarts.It’s also in general a good place to centralise account management (esp. if parts of the game would need to be reloaded if another account is logged in!)
Lastly, although this is more of a side-effect, but it gives a good place to shows recent news/posts of the company about their game to players, such as when there’ll be downtime, in a way that’s practically impossible for the players to miss.
Managing updates, versions, mods, and settings can be done from a launcher instead of the game itself and it’s often easier that way. If you wanted to adjust mods in-game you’d need to restart the game for changes to take effect.
Before Steam became the universal launcher, lots of games had their own. Minecraft isn’t a Steam game so it comes with its own launcher.

This completely depends on the game. There’s nothing inherently about mods that requires this.
The only game I can think of that doesn’t actually require a restart is Mechwarrior 5: Mercenaries. I’m sure there’s more, but that’s what I’ve encountered.
That’s because it’s easier.
Most games do not even have official modding support, Minecraft included. Most are only moddable because they use some interpreted programming language somewhere in their game, which people found ways to read and inject with their own code.
This works by replacing assets, config files or even by injecting binaries into pre-compiled games, as well.
Minecraft is in a pre-compiled language (Java), but so is Skyrim (C, C++) which is famously modded (although most mods are written in Papyrus which is an interpreted scripting language, the game itself wasn’t).
Most mods for Tekken (C++) also work this way; they simply replace assets and config files.
Luanti is kind of the obvious example to point to, with it being a community-developed engine for Minecraft-like games. But yeah, what @Azzu@lemm.ee said very much makes the difference. As opposed to Minecraft, Luanti has modding support built-in.
To answer your third question about Minecraft specifically, you absolutely can run the Java version of Minecraft independently of the launcher. It’s just a Java package. Find it and load it with your Java runtime from the command line and it’ll play. Without authentication from the launcher, however, you will not be able to connect to Realms or indeed any multiplayer servers that have authentication enabled.
But for that reason, the Java version specifically of Minecraft is famously easy to pirate, provided you are fine with being limited to only playing locally or on pirate servers that have authentication disabled.
In the bad old days this was in fact the only way to play Minecraft in non-supported platforms (i.e. not Windows).
Other than a handful of games where it does literally nothing but force you to sign in to something (such as Rockstar’s Social Club shit or the Xbox Live for Windows thing from years past) most of the ones I see having a launcher just for the one game are ones that let you adjust settings before starting, choose a renderer version to use (Vulkan, DX11, or DX12, etc), or, like as is with Minecraft, allows you to have a safe modded version kept separate from your vanilla game or to manage saves.
You can also, in most cases, bypass those launchers by just launching the preferred executable in the game’s installation directory.
It usually makes it easier to centralize authentication. But more importantly (from the company’s perspective), it gives the game producer a chance to upsell other products and micro-transaction content.
upsell other products
I don’t think I’ve seen games do that, not even to advertise other games from the same publisher/developer. But then, the only five games I’ve played with a launcher are three MMOs, Genshin, and Honkai Star Rail.
Don’t forget that the game producer can now collect and sell data on their customers’ systems.
With no privacy laws on the books in the USA, there’s literally nothing stopping them, and a lot of incentive to do it.
They can and do that without a launcher LMAO
Minecraft is special. The launcher sets up a bunch of Java stuff and other game configurations. And it downloads updates and handles authentication. Technically you don’t need it, but it makes it a little easier for the developers and the users. There are also third party launchers with additional functionality like downloading mods.
Other games often pretend they need that stuff when in reality they just want some more tracking that is not in the game itself.
Technically you don’t need it, but it makes it a little easier for the developers and the users.
For that matter, if you poke around in some games’ files, you can find the actual game.exe and launch it directly from there, bypassing the launcher. You just bypass the authentication and compatibility checking as well.
This also works with any Unity game which prefers to launch through a launcher.
If it’s an online game, like an MMO, they might put your account on timeout if you keep playing some outdated version of the game, though.
I’m honestly surprised you can even connect to an MMO with an out-of-date client. On the few I’ve played, at least, a version mismatch is an automatic refusal to connect.
I’ve had Black Desert letting me play a bit with an outdated version (I didn’t know there were updates, I hadn’t used the launcher for a while) but it gave my account a time out of 10 days after my play session.
I was also surprised it didn’t just go “Nope, update first!” immediately, I kind of expected that would be the case if I didn’t use the launcher.
That, my friends, is also how you play games from the epic store. And how to bypass steam as well.
Doesn’t work with every game, though. Some have DRM that depends on the launcher and/or authentication.
