I'll agree that cutscenes do take alot of time to make.that is why most of my gameplay time is in actual play.My dungeons are enormous in size.The dungeons being the only real way for you to acquire what you need to progress your character.
The stores in my game only sell basic weapons whereas the dungeons contain many important items that you will definitely need if you intend to conquer the harder and longer dungeons.Also the dungeons are not just walk,kill,move blocks.Certain monsters must be defeaten to acquire items used to make medicine and forge.Also most of my dungeons have nearly 40 kinds of totally different monsters.This alone makes for alot of game time if you want to explore all the routes you can go.On the other hand these dungeons are completely optional as are most of my side quests and mini-games.
