Rebels in the sky is a P2P multiplayer game about crews of space pirates roaming the galaxy to play basketball against each other. It's basically a basketball managerial game with some pirate-y stuff. It's a P2P game with no central server, built on top of libp2p. Players interaction are limited to playing games against each other and trading pirates.

The game runs as a terminal application, meaning that you just need to run it from your terminal.

You can try the game over ssh without installing: `ssh frittura.org -p 3788`

My server is not very powerful and there is a limit to the number of concurrent players, so if you like it I would appreciate it if you could install it (https://github.com/ricott1/rebels-in-the-sky?tab=readme-ov-f...) and run it locally :)

Here is a trailer (not of the last version, so some little things are different): https://github.com/user-attachments/assets/aaa02f04-06db-4da...

Interesting idea to have a completely p2p game! What cross-user interaction do you have in your game?

Thanks:)

Basically users can interact by playing basketball games against each other or by trading players. This sort of interactions are handled with something similar to a TCP handshake, since we must ensure that we end up with a consistent state at the end (e.g. players are traded consistently).

Because of this, it is not easy to have 'real-time' interactions: for example, when challenging each other, players only agree on the initial conditions of the game, which then is simulated independently (and deterministically) on both clients.

Cool!

Makes me think of blockchain: it is also a tool to ensure "consistent" state changes. Have you thought of moving your game on some blockchain?

For example, XAI is a blockchain specifically designed for games, you should check it out

this thread makes me want to build a platform

I tend to lean toward the raft protocol vs blockchain due to storage

blockchain is too slow and completely inappropriate.

in case nobody told you, you’re not allowed to say blockchain on HN

Talking about blockchains is fine, pretending they are somewhat apt at solving a problem that isn't money laundering is what will get you frowned upon.

raft is too non-deterministic. Something like paxos is probably more appropriate; the write-once property is exactly what you want here, and it is deterministic.
