So how useful it is in practice?

It's useful for quite a few things in practise:

  • You can be sure software that is packaged with nix will behave the same on different computers.
  • You can avoid dependency conflicts.
  • You can automate some things that would otherwise take multiple (mostly manual steps) on other systems.

This video shows off some of the cool things you can do with nix: https://youtube.com/watch?v=6Le0IbPRzOE&feature=share9

How do updates work?

You update a programming by specifying the latest version of a program in config and rebuilding.

You update the OS by pointing to the channel you want to use and rebuilding.

You can time travel back to a previous state if anything goes wrong.

Can it play Crysis?

I expect so, some people.do use nix for gaming.

never had that issue before, as long as they have the same version and config

avoid dependency conflicts

I have those on Gentoo sometimes, possibly because I overloaded USE too much, but that's not something I have to deal with on Debian/Mint.

You can time travel back to a previous state

wasn't that possible before with snapshotting (btrfs/lvm)?

If it allowed me to avoid systemd, I would be willing to give it a go. Perhaps I will try it in a VM, but it's not going on any baremetal for now.

Then you are very lucky. "It worked on my machine" is a meme for a reason.

I haven't used snapshotting with those before. I guess the difference is that with nix it is done by the package manager by default, with btrfs/lvm you would have to set that up independently (please correct of this is not the case).
