Quest designers and mappers don't program your graphics, and graphics programmers don't design quests or dungeons.
You don't understand :confused:
Think carefully as I try to explain now.
The many many many more quests, dungeons and detailed locations (as well as the design/idea to make them)
takes time. Lots of time.
Every gaming company has a budget.
Bethesda's games have always been these huge open world games with tons of locations and stuff to do. More than any other game. This has always been their main focus.
Therefore, the main share of their budget goes to this. It takes time, and time is determined by how many you hire, which is, in turn, determined by how much money you have.
The reason this affect graphics is because less people are hired to focus on this. Less people means less time. Less time means that the graphics won't be as top-notch as Crysis, of which Crytek surely had many many more employees focusing on the development of technology and graphics.
Todd Howard said some time "We can do anything, but we can't do everything."
This is the connection, do you see it now?
