@Berker It shouldn't be only multiplayer games. ANY GAME that has some online-only component that could reasonably work offline, should also work offline.
The HITMAN World of Assassination (trilogy and 'game') is famous for this. Quite literally, out of your (at-most) $130 you pay for the Deluxe + all the DLC, you only get to access $50 worth of content offline. This means, 35% of the game can be played offline.
- All of the escalations you paid for or included in that $50 are not available.
- The Seven Deadly Sins (count as escalations) don't work offline
- Cannot unlock content, challenges, or work towards mission mastery
- Cannot play Freelancer mode
- Can't play Sniper Assassin mode (even if it has no MP component anymore)
IOI is being unbelievably absurd and locking all of this behind a server, when this should work offline just fine. A community-developed open-source private server (Peacock project) isn't a solution.
