Some clients already have their main game features built, the only thing being left is the integration of database for user authentication, data, and file storage. Thus, and we offer co-development for database features. Generally, when a game studio, or indie game developer approaches us for a database solution for their Unity project, and they don't have a strong preference on which to use. We suggest Firebase, an all-around cloud service provided by Google. If they need a more popular solution, we can build PlayFab or Photon for their database and multiplayer networking features.
The advantages are apparent: straight-forward UI, ease to integrate,
and the potential to scale for larger projects if the games gained a strong audience.
Actually, one of our client from Brazil, has been managing more than 500 new players records stored in the Firebase Realtime database for their VR game, which we helped developed, in merely 3 weeks of their beta testing in their local area. And they have been satisified by the the reliable and user-friendly Firebase features, considering their business being a non-tech photography agency.
We have worked with 3 clients on the integration of Firebase in the past 2 months. Their projects were for different platforms, which also gave us to ability to experience how well Firebase works on nearly all major platforms.
