We don't own digital copy forever if steam is bankrupt everything is gone, if you still remember that day o2jam Malaysia forgot the company name when they out of business they forever gone all the dlc song pack i buy forever gone .

reputable company like steam probably until the day i die or the steam big boss is dead probably still there

even steam sold to bigger company probably still there since the company is earnings money and money drop from the tree probably if you wish them closed for business technically very hard,

unless special case I example ww3 i mean nothing is left digital or physical if involved in war if everything is burning down XD

Physical copy well no one wants multiple CD/DVD to install the game, even after installing the patch alone also don't know how many gb already

Unless the physical copy they come up with something like larger storage like thumb drive

Else everytime buy game nowadays the file size too big also come with more than 5 physical CD/DVD i literally don't have space for that 😂
