So these two series have been rivals for years and though a thread like this will give an obvious answer if we stack the whole of each franchise against each other seeing how this is an FF forum, but I'm going to make this interesting by pairing entries against each based on their original release so we can view this from a Japanese perspective a bit. I am going to ignore spin-offs and DQX though.
So with that said, which did you feel was better in the following match-ups:
Final Fantasy vs. Dragon Quest II
Final Fantasy II vs. Dragon Quest III
Final Fantasy III vs. Dragon Quest IV
Final Fantasy V vs. Dragon Quest V
Final Fantasy VI vs. Dragon Quest VI (one year off, FF predates)
Final Fantasy IX vs. Dragon Quest VII
Final Fantasy XII vs. Dragon Quest VIII (two years off, DQ predates)
Final Fantasy XIII vs. Dragon Quest IX
Let's see if we can get five posts since many members here haven't played DQ.
