I'm really surprised no one mentioned Terra Invicta!
Basically if the Three Body Problem series was a Grand strategy game.
In terms of grand strategy it is quite grand. So massive and complex that even 100 hours in, I haven't completed a game.
That being said, it's so addicting. I haven't really played any other Sci-Fi games where you can take over multiple countries on Earth, take over other bodies in the solar system, and field space Navy to defend the planet.
I never understood this one. I have ADHD and autism and I find gambling boring as hell. With maybe the exception of blackjack. Where my autistic brain tries to count cards.
I remember the day I turned 21. I decided to try out a casino. I spent $50 there and promptly left. Maybe I just lucked out and they didn't hook me with an easy win early on?
I'd much rather spend $50 on a video game that I can entertain myself with for hours.
