Rumored at a development cost of a whopping $30M USD, this free-to-play mobile game reportedly earned less than $1M in its 1st month of release, slotting it at 215 among mobile rankings - https://archive.vn/S4HZ2

As the failure threshold is an average of 50th place, the release was catastrophic. While it's not clear why Sakura Wars was considered worthy of such expense upon its reboot, it's a stark reminder of how digital is akin to owning nothing.

Even as Sony recently reversed its decision on shutting down PS3 and Vita purchases permanently, but not PSP, they will inevitably pull the plug again at a future date. The same fate will follow for gacha games, irrespective of ranking.

The only way to future proof is to own physical, be it cartridges/disks or backups via piracy, and disseminate copies.
