no games realy force you to explore anymore, i mean there is plenty of exploration to be had in fallout 3, and since enemies scale with you nothing is really dangerous, for the most part, if you did choose to just strike out and go wandering around. but if the game had no compass and quest, points of interest indicator and people were forced to just wander around looking for everything, many gamers would have hated it.
games that made you find things on your own are long dead, last mmo that did that was asherons call, you had a basic map with some of the towns marked on it and some basic portal spots and a few dungeons but the vast majority of the world was unmarked, even the epic quests people had to scour the world to find the clues to start them and then find the new dungeons. So you had to keep a list of location coordinates and map points of interest and crude landmark path finding on bits of paper and index cards.
Ahh the good old days before wikis and walkthrous were all over the internet.
But then games started more and more to hold your hand, no fogs of war no lack of quest checkpoints, games told you "go here stupid" where old games just said "go somewhere stupid" and old games were more than happy to get you killed wandering around.
I think it would be far more interesting if this professor focused on the hows and whys of why we have liked out games so limited in scope. yea it can be frustrating not know where exactly the next town is or where the quest you are supposed to be doing is, but the great games had a abundance of things to find in the world, secret stashes of treasure, runes of power, hidden mega bosses that would kick your arse but promise untold wealth and power if you managed to beat them at some point.
Were we got off that track of having fun exploring and why social and societal causes lead to it, was it just game makers dumbing things down? or did people change over the years to force game makers to simplify their games so they would not get angry and not play.
what came first the chicken or the egg more or less.
all that said ultima series was brutally hard period. take away the lack of maps and direction and you still had a game that was going to kill you often and make you earn your way along.
