Immersive Sims are FPS games set in believe/realistic maps and have a high degree of interactivity and/or depth. Being able to interact with all the doors, computers, vending machines, toilets, etc. I can’t remember if it was Deus Ex or Duke3D that first coined the term, but a lot of Build Engine games were described as immersive sims (and where I first heard the term) and the biggest things that set Duke3D apart from Deus Ex is Deus Ex has the RPG elements, like character stats, augments, and dialogue trees.
Honestly, tho, the genre is vague enough that if it simulates enough reality in a way that makes you feel like you’re actually in the game world, it could be called an immersive sim.
