The best JRPGs around are known for featuring optional content that's a joy to uncover, especially if this secret content includes boss fights that house great rewards and tantalizing power. Players will love fishing out these challenges and optimizing their party to ensure that these enemies can be taken out with a sound strategy. However, while JRPG fans love bosses who are as challenging as they come, there's a limit that, when crossed, can turn a tense encounter into a frustrating one.
