Which do you prefer and why?
For me it's definitely Final Fantasy.
One reason (among many) I don't prefer Dragon Quest games is:
"Liquid Slime is defeated!"
*presses A*
"The enemy is defeated!"
*presses A*
"Hero receives 10050 exp!"
*presses A*
"Hero steals Seed of Strength!"
*presses A*
"Hero receives Seed of Strength!"
*presses A*
"Hero places Seed of Strength in the bag."
Every single battle.
