I think it might have more to do with modern gamers. Budgets were not better back in the day.
At the risk of sounding like an old timer, games used to be way more complex.
Stories were good or bad but there was a lot more open world/choices in games.
How many modern games do you build something then interact with that world?
And random encounters are a great filler. In Fallout 1&2 you had to be ready to fight anything. In the later ones you know if you will be fighting humans, monsters, ghouls etc.
Random encounters can still be "hand-placed" since some games define the kinds of enemies that appear in a given area, but I see what you mean. Both can be done sloppily. To me, not being able to anticipate what you're going up against in a fight without being killed by it first
Do I need to remind you you're on the Dwarf Fortress forum? When you google "most complex game ever" the first thing that comes up is DF. You're surely blind if you think that there isn't a bevy of options out there.
We're drowning in open world games today that are bursting with choice. If choice is all you want, there's never been more.
Dwarf Fortress (again), Space Engineers, Starsector, Cortex Command, Survivalist, Subnautica, and Factorio, are just a few, excellent, modern games in my library that easily meet that criteria.
Games have always been beautiful and people never stopped having good ideas. The games that came before have inspired the designers of today. With the indie wave, games have become more complex, varied, and free than ever before. We are living in a golden age, and you're squandering it by not making an effort to take in what's around you.
I'm not being a jerk, I really did want recommendations and value your input. I'll check the ones you mentioned out. And (of course) I've played DF. It is the most complex game out there. I wish there were more. The ones I've played that are pretty complex are Rimworld, Unreal World,Cataclysm DDA, Zomboid, Elder Scrolls, MegaTraveller, original Wasteland, Fallout 1&2, etc. So except for Rimworld and Zomboid the rest are all really old.
Deus Ex would be great if it was truly open world. If I remember right the original was pretty open.
The more choice and simulations in game the better.
There are a lot of good game "ideas" out there but the studios either never fulfill their promises or go broke trying. Or they leave it to modders to fix the flaws.
Can you tell me more about your recommendations? What are their best features?
