It’s kind of sad that one of the greatest video game series is on hold for now.
Conspiracy theories, multiple ways of solving a mission, game lore hidden in computer inboxes…
Are there any (pre-2010) games that gave you the same feeling or do a similar thing?
Not pre 2010 but Shadows of Doubt is worth a mention. You are a former cop turned private eye, solving crimes in a procedually generated city trying to make ends meet. You pick locks, hack emails, use air vents and “Jensen your way in” to chase leads, collect evidence and bring justice that the megacorporation government won’t.
It’s far from perfect but is the best “Deus Ex 1 we have at home” I’ve seen.
