Lets say you live in a world where the world government has decided people are getting too addicted to the internet and ordered the internet to be shut down for 5 years. The 100 GB of storage is all you have (excluding essential system files for your Operating System). You have 24 hours before the internet is getting shut down. What do you download?
A collection of older and therefore smaller games. A bunch of music in mp3 (or maybe something like AAC or OPUS). A bunch of ebooks. A handful of my favorite TV shows and/or movies heavily recompressed, like maybe 720p.
Don’t rule out midi or mod music file formats
