Did you miss that in the example the character checked the bridge (randomly empty at the time) then went away and came back two hours later, at which point the bridge (again randomly) had an enemy on it?Oh I get all of that. None of those system have you roll randomly for monsters after deciding to explore the bridge in the way described above. In terms of travel the roll would be made and an encounter result might begin the bridge scene, or a wandering monster roll might be made at some point during that scene if the players spend enough time. I'm not denying that people play like this, I'm just struggling to think of game were this process is the same as the one set out in the rules.
That things can change as in-game time passes isn't against any rules anywhere, I don't think.
