If you like this kind of urban exploration of infrastructure, but you can't get out and do it; I cannot recommend the game INFRA enough.<p>I believe the company who made it originally did 3D visualisations of infrastructure for companies/goverment, and their environments are incredibly immersive because of it. Perhaps the best looking Source1 engine game in my opinion.<p>You are an engineer tasked with investigating issues with a particular dam, but as you dive deeper, exploring operational water infrastructure, train stations, power plants and abandoned facilities, you begin to unravel a story of corporate and government corruption and espionage. There's no combat, your main goal is getting through the different facilities, fixing stuff along the way if you want, and taking photographs of all the stuff that is broken.<p>It really hits all the exploration and engineering nerd itches.
