Games with similar development times, far less staff on the project and made with unfamiliar engines have been much better so I agree with Knight that having a short development time is not a hindrance, and is sometimes a benefit. Fallout: New Vegas, multi million selling and widely agreed to be much better than Fallout 3 and one of the best rpgs in recent years, similar development time and unfamiliar engine. Baldur's Gate 2 had a similar development time and far, far, far more content. Kotor 2 similar development time and very flawed but made by twelve rather than a couple of hundred. Icewind Dale 2 made in ten months etcetera.
Edit: THIS IS MY PERSONAL OPINION.
