Krogan32: I saw that. However, he never stated a %. So, the "80-90%" is just you making up falsehoods to fit your agenda.
mrkgnao: If you go the Hitman's game page and search through the reviews, filtering for reviews by verified owners, you will find one by emme that does mention percentages. What he states has been confirmed by several others who have played the game. Here is the text, just in case:
"Bulk of the game behind online-only DRM
September 23, 2021 Verified owner
The warning text that has been added does not adequately describe the extent of the game that is locked to online-only.
All progression - mastery levels, challenges, and consequently unlocks for different starting locations, stashes, equipment and weapons - is also locked behind the online mode requiring connecting to the game's servers. So you cannot ever use anything other than the default starting status, I would consider it similar to a demo. The first words of game description itself are, "Experiment and have fun in the ultimate playground" - this is more of a sandbox than a linear, play-each-mission-once style game.
I have this game on another platform, and enjoy playing methodically going through each mission to fully explore and complete it as much as I can before moving on to the next. I have 56.5 hours recorded over the tutorials + first two story missions. To be generous, that a 'default status' run of these levels took me one hour each, that is just 4 hours, or 7%.
93% of my experience of the game was reliant on content that is locked behind online-only DRM, even here as being sold on GOG.
There is a text on the sidebar "DRM FREE. No activation or online connection required to play. ", but I could not consider it is true for more than a fraction of the game's content."
Taking the opinion of one individual who felt strongly enough to leave a scathing review doesn't make it fact due to the extremely biased nature of the source.
