What is a measure of how heavy an object is?

In this sentence, "epic" means the same thing as "great". The main difference is in the fact that this word would attract the audience more easily than the word "great". With this word, the writer tends to be more authentical and leave a bigger impression on the audience, by representing an exceptional game, characterized by its heroic actions and adventures.

This word makes the paragraph more interesting and appealing to the audience.
