It is. Very atmospheric, and I'm sure there's a whole lot more depth to things like combat and crafting if you're interested.
For me it's just an easy and accessible story RPG. The text-based dialogue and turn-based mechanics make it ideal for on the road gaming IMO. You can look up from your screen or suspend and drop the Deck into your bag at any point.
The writing is great and the game feels much, much, much more fluid than the actual old games it is based on. A lot of love and care has been put into this. It's very affordable and the most battery-friendly game I've played. So when you start up your Deck on the train and only have 15% left, this gives you much more enjoyment per battery charge than anything else.
Full disclosure: I happen to know the artist who did the character art.
@Telorand@reddthat.com, I second starting out with Home Manager on your current Linux or Mac. It's a great way to learn all about Nix, while keeping the option to move back to a shell that is not managed by Nix and having the option to go back to a shell that is not managed by Nix (I had zsh in Nix, and Bash native) and still being able to boot your pc when you mess up in Nix.
The real advantage, as @BlastboomStrice@mander.xyz said, is in being able to use recent packages on any Linux and MacOS. Home Manager gives you that. I first started with a basic Home Manager config, then learned about the Nix language using some simole puzzles (the first Advent Of Code days), then the module system, finally flakes so I can use packages from 24.11 stable in Home Manager on top of other Linux OSes.
This way I could take it step by step instead of the rocket jump that OP did. Hats off btw @BlastboomStrice@mander.xyz , you provide amazing value with your nixos plan!
