Indiana Jones and the Great Circle disc for PlayStation 5 will have only 20 GB of data: more than 100 GB will have to be downloaded from the Internet

The physical edition of Indiana Jones and the Great Circle for PlayStation 5 contains only 20 GB of data on the Blu-ray disc, which is less than a quarter of the game's total size of 125 GB. This means you'll need an internet connection and a download of over 100GB of data to run the game.
Here's What We Know
Although PS5 Blu-ray discs can hold up to 100GB, Microsoft and Bethesda have decided not to use this capacity in full. Other developers, such as Capcom, released games on two discs. However, in the case of Indiana Jones, the disc actually serves as an activation key rather than a full-fledged game medium.
This approach raises concerns about the safety of games. In the event of a Sony server outage, players may lose access to the game even if they have a physical disc. Some players believe that this devalues physical media and calls into question its relevance.
Indiana Jones and the Great Circle will be released on PlayStation 5 on 17 April.
