Skyrim does offer the player plenty of opportunity to roleplay and you don't have to pretend in any way that things are happening when they are not, in the sense in which you mean it.
Skyrim like all of the previous TES games provides a canvas for you to use, in pretty much whatever way you choose to use it, if you are unable to paint on that canvas, is that Bethesda's fault?
It's difficult to imagine a series of games MORE suited to roleplaying.
In my opinion, obviously.
Yes, it is true they make a wonderful canvas. However, I think it is important to point out there IS a line. I hear that view expressed so frequently, whenever some negative is brought up about the game, where they could have done a better job of something, like lore or quest options/choose-your-own-adventure dialogue, yet these arguments often fail to define that important line.
To put it plainly, I would not consider an empty box to be the best possible role-play environment. To say "if you can't have fun with it you lack imagination" does not counter the fact there is a certain expectation of the genre, and that expectation, and hence reason for consumer purchase, is NOT to fill it all in yourself.
Role play is a GUIDED experience. Since the days of Dungeons and Dragons, where a lore master would define the context, rules, and limitations by which the game would evolve. In that respect, there ARE many aspects missing from the latest title, specifically the depth of options of choose-your-own-adventure style quest and dialogue interactions as I mentioned previously.
They do a fairly decent job of filling in the back-lore, however the bulk of this is done with static books. That isn't necessarily a bad thing, but in some ways one might say it is now an empty box with some books thrown in.
Granted this anology is hardly accurate, as there ARE plenty of things to do in Skyrim. There are also plenty of complaint threads that pick apart unimportant minutia, so I can understand the terseness and frustration of fans at this point seeking something more expansive on the forums. It is still, at the end of the day, a great game in its own right.
People are frustrated though. Many have been experiencing the lull of new depth-centric virtual worlds of late, and looked to Skyrim as the next revolution in lore, adventure, and storytelling. What they got was some rough sketches, broad strokes, and action packed new engine mechanics. It isn't that it failed to deliver the level of such that was expected from Oblivion, but more that the lore and storytelling wasn't light years beyond like the graphics engine.
That said, I never downloaded the space ball thing, nor do I see such technology really having much a place in TES. As others have said, just a gimmicky thing they through in for kicks. "Take this, as a token of my e-Steam!" XD
