NO, the areas in 1.0 were absolutely horrible. It took 9 minutes running from Gridania (the city itself) to the first Camp to the west of the city...ON FOOT, 9 minutes! With Chocobo, it was 5. The areas were VERY bland; everything looked the same, and I hated it. ARR is well crafted and a lot of the people who did work on FFXI helped with ARR's development, such as the outdoor area zones. Seriously, La Noscea is just as well-crafted as Rolanberry Fields with the scenery. ARR has more life than 1.0 ever had in the field zones, I'm serious. 1.0 looked like a lunar landscape with some foliage here and there, ARR is not like that.
At the time with FFXI, they had the assets to make big areas because the graphics were not cutting edge at that time. Plus they could reuse some assets (such as the towers in Sarutabaruta, the rivers there, etc.) to save some time.
