But you are comparing and yes, country do play a factor in art design. Blizzard has a unique look to their games, sort of a trademark. I wouldn't say SE has a similar look to their games but individual producer have a certain niche,
Tetsuya Nomura for example.
Now if by "smooth texture" you mean polygon counts, WoW has added models and levels with higher polygon counts with each new expansion, but not everything in the game has received this graphics up, BC is basically the same models it had at release though improved graphics cards and directx upgrades makes it look cleaner.
As for FFXIV, console support is a fact because while PC continually upgrades itself year after year, ps4 hardware remains the same until a new console comes along every 5-6 years. This was a reason SE dropped the PS3 support.
If you are curious about FFXIV 1.0, watch this:
