I can’t talk about much about the game as it’s in development and unannounced, but it’s a 3d adventure game. We use LiteDB to hold all game state: objects on the ground, button/switch states, ai variables, inventory, etc. LiteDB allows using C# classes directly with the BSON mapper, allowing easy interoperability between the database and using the data in game. LiteDB allows using MemoryStreams which are convenient for loading and saving from a binary storage like a cloud service or a file. It’s fast at querying, but we’ve had issue with upsert performance so we perform all upserts at once in a separate thread to not impact the main game thread. Over all has worked well for the project and has had minimal issues over a year plus of development.
