The main idea for a database is for storing data on disk and as a cheap man's way of sharing data across processes that are running at the same time.

If you don't find yourself needing to share data between two processes at the same time or storing data on the system, you may never need it.

SQLite can actually be used as a decent save system for a video game since you can just store into it and read from it. You could actually do a "Mass-Effect Style" storage system where you can store items from Game 1 and read it on Game 2. You could actually have your studio share a SQLite DB and have your games reference whether a user has played another one of your games.
