The game state being a SQL table just kinda triggered a memory of a year of optimization for me. One thing I'm still unsure of being a good decision or a bad one, when I wrote my casino in 2010, was having every remote call update game states on SQL tables that were used as the source of truth. With multiple players you can imagine that there would sometimes be issues. Some of the deadlock problems early on were horrific; scaling was a nightmare. But everything was atomic. No risk of lost data beyond one turn not reaching the server or deadlocking, nothing like a huge nodejs process choking on everyone's calls at the same time, or losing its memory. You always had state.
Looking back it seems like not a terrible design pattern for multiplayer turn-based games, if you can work out the kinks. Atomicity guarantees at least that there is a consistent state that won't get lost. Doing that read/write loop for an action game? Pure folly, but it's pretty funny to me.
Yes, this is fantastic! I'm trying it right now. I look forward to the day when LLM inferencing can be done in a sql query and take less than the age of the earth to do something. This works way better than I would have expected, since, well, it's sql all the way down.
I noticed the cedardb.com blogpost on the project is slashdotted at the moment, but the game itself plays just fine.
> The game logic is just ~5900 lines of SQL. While this sounds a lot, it’s definitely less than the original C source code which does the same in about 9000 lines!

Nice
