The little words have taken over my life and they are Kerbal Space Program.
It’s been a long time since a game like this has kept me wanting to go back for more. I can draw parallels to when the original Sim City came out and how it was used within schools and rumoured to be used in proper town planning. Even more strongly, it reminds me of Minecraft. Minecraft has a massive fan base and a massive mod community. It started out as a beta and gained momentum before being officially released. It is also used in a similar way to the original SimCity and has been taken up be planners and educational institutes alike.
