Consider porting the database to SQLite and/or Postgres

[avioletheart]

for running the game locally on a player's machine, it's a lot easier to use a single-file sqlite database, rather than setting up a microsoft sql server; for cloud hosting, postgresql is a lot cheaper and easier to run

while i generally don't like ORMs like EFCore, the abstraction might make it easier to port to other database engines in this case.

In this case I think moving database should be as simple as simply changing the database provider in the Program.cs file.
