Nakatomi Space
This post reminds me a bit of some games, which would normally be called "immersive sims". One of their biggest draws is how they let you interact with the environment in such a variety of ways. A blocked-off entrance isn't a set scripted objective or a tool for the developers to get you to go elsewhere - it's an opportunity for the player to find a creative solution.Blow up the barrier. Pick a lock. Break a window. Reach through an opening to press a button to open another door. Enter from vents or sewers. Alert an NPC so they open another entrance to check it out. Shut off the power elsewhere. Etc.It's so much fun to have all those options with how you interact with the environment, instead of it just being static and 1-dimensional.
