It has a lobby, a reading room, and an office. Oh, and two human storage areas.
It has four or so students, and few more faculty members.
most of the time, faculties can be found in their respective rooms, drinking some mead.
In the mean time, students can be found in the lobby area, practicing their magics... at the windows! (This I assume is a safety hazard no doubt)
Now I know that everything is Skyrim is a scaled down version of what they actually are in game lore.
For example, I know that the province of Skrim is suppose to be the size of the state of Washington (or something like that), but is scaled down in game for obvious reasons.
and I'm sure in lore, the college is really quite prestigious place, only scaled down for gamer's convenience
However, I think the current size of the college is really too small.
Sure, small size means that I can find all the NPCs I need in just a few steps, and that's all great, but it has its downturn too, and a big one.
The downside of the small college is that the scene is nowhere near believable, and when the world is not believable, I have hard time immersing myself into the world.
When the immersion is broken, I no longer feel like I'm roaming the great land of Skyrim. Instead I feel like I am seating on a chair, playing Skryim, in my room, which is much less exciting than roaming the lands of Skyrim to be honest.
So I hope, in the future, Bethesda would make things a little bigger.
Maybe that means more generic student NPCs and more time getting lost in the college, but that's just fine in my opinion.
I don't mind there being bunch of NPCs with no quest for me, just occupying space, because that will make the experience much more believable.
This also goes to the cities and villages, though they were much better in comparison to the college of Winterhold. I think the size of Whiterun would be fine for average cities (like Morthal and Dawnstar), but cities like Solitude, and Whiterun still needs to be bigger in my opinion.
