Apart from a few glitches here and there, the game feels really complete. The story is really well made and the writing is top tier. If you come for the RPG elements of talking to every NPC and finding a lot of fun dialogue, you’ll love it.
If you want something without combat, although not fantasy, Disco Elysium has become my favorite CRPG ever.
I would just have Postgres running statically on some solid hardware. It’s easy to configure permissions and connections, too.
Not too hard to set up streaming replication for a hot standby if you wanna be sure (or offload some reads).
I use Postgres btw
