But not all epicness is created equal. This isn't a fantasy novel, it's a game. Colorful splash screens and backstory will certainly embellish it, but they can never replace the core!
We have different perceptions of games. For me, a game is—among other things—a soul. When you start to believe in the game world, to feel it, that's when you get more pleasure. Of course, this doesn't apply to all games, but some people need a plot, harmony between its components, and other such things. Heroes could be categorized as esports games, where there is no question of any plot, or it could be seen as a game that is more elevated in terms of the importance of the game world. But a race must harmonize with the world regardless.
