I don't believe you've ever played Fallout: New Vegas.
"Invisible walls" aren't an engine limitation, by the way. Some of the very first quasi-3D game engines didn't have invisible walls, and some of the most modern games on the most modern engines do. It's a development decision.
Except for the steepest mountains you could end up almost anywhere. I remember getting into Skyrim dungeons by the back way by scaling cliffs.
