You can read the books on the shelf? Like...the repeating texture of books that look like they do nothing? The ones that go through the whole library? Or am I missing something.
It's not really you who miss something, it's rather the game. ;P
I except the majority of PS players don't know you can read the books. It is because, that by default you except that you can't click a thing you see (like in html, we have links, which change when you move mouse over, think how it would be if they wouldn't :\).
I proposed few times, that a cursor (or some other indicator) would change if you move mouse over something you can click and you are in range. For example:
a book shelf: cursor change, range: 2 m
a random item in he world with description: cursor change, range: 2 m
a hidden brick in a wall: cursor change if you have skills, range: 2 m
Everyone who can make it happen, probably know about it already, but i think it is good to recall this. It is almost critical feature, because you put efford into describing items and other stuff, but majority of the people don't even know about it.
