Short Answer: No

Long Answer: Yes.

Ask any developer what they wanted with their project, and 99999 out of 100000 they'll say "Time". No matter what you do in a given time frame, you could have always "Done more" with more time. This goes back to one of my personal beliefs that "Perfection is a moving target". What is perfect one day, isn't another. The Modding community is a great example of this. How many "Mods" are ever truly complete? Many are ongoing projects that span literally years, the difference is that they can push out an extremely (And sometimes catastrophically unstable) sketchy product and slowly refine it over time. Consider that a modding community doesn't have to prototype technology on the same scale as most developer's studios and you really can't fault them.

There's a fine balance between cranking out games quickly, and making good games which take a long time. I think Bethesda is walking the line quite well, they have used a different engine each time, spending around 3 years on each game, and this keeps the fans satisfied and the business profitable. So I think it's fine how it is. And how many people would really wait another year for an improved Skyrim?(That was rhetorical) Not to mention technology would've moved ahead to the next generation of consoles and computers.

Well, it could have all the development time it wants- but in a few years new consoles will come out (And one already had), and buying new consoles isn't cheap. hmy:
