And easy way to compare it would be to compare chess to sports. One is the exercise of the mind and the other is an exercise of the muscles. |
My very first thought after reading the OP was about Chess. In my opinion, Chess is the most amazing game I've ever played. Because it's turn-based, it becomes a tactical battle which requires and rewards thought over reflexes. When a battle system is real-time, on the other hand, it has to be dumbed down to a certain degree or most people will be crushed. A different skill-set is required.
Personally, I love difficult turn-based games to death. I will always, always choose them over active battle systems. I have enough games that test my reflexes, I want more that test my ability to reason.
Now, that being said, I still judge each game on its own merits. I liked FFXIII just fine and I'll certainly not whine about FFXV because it's different. However, yeah, I really want more turn-based RPGs.
