If there is one great era that has been incorporated in different entertainment mediums, it will be the Medieval Period. There are three reasons why this era is a great theme in different entertainment mediums. One factor is because this era is so classic and calm where life seems to be simple but happy. Second factor is because this is the time where Kings and Queens are prominently ruling the kingdoms. Third factor is because the vibes and environment of this period is very relaxing and at the same time, entertaining.
There is no surprise that even in flash games, this era is being incorporated. In fact, there is one good example of a game that applies this theme and it is called Kingdom Rush 1. This is a game where magic and Kingdom exists.
