This means that you yourself can only BE one character - the one you are looking at. There is no space for you to fill with your own information.
So Zork was the best game ever, because you had no idea what your character was like at all? Did we just stop making good games when we started drawing pictures for them?
Your argument has several flaws. Firstly, neither all old games not all new games are like what you describe them to be... plenty of newer games are first-person and mostly let you see, say, your hands, leaving everything else up to your imagination.
Secondly, and perhaps most importantly, the value of being able to roleplay in your videogames is a bit... subjective. DnD is not better than Call of Duty for everyone... a lot of people find the lack of defined detail unimmersive, but certain people love it. Different games exist for different reasons, different customers, different moods.
Fortunately, though, we have a vast array of games to choose from. If old games are your thing, then you're in luck! There are a lot of them out there that can be gotten on the cheap, and there's a lot of good gameplay there... but it isn't better than the new stuff. Well, okay, it's objectively better than a lot of the new stuff, but that's more a matter of style, execution, and artistic vision than it is of the actual technology that people had to work with.
