For a game such as this I think it’s important to have more of a backstory for each Merc than just what they do for their team. I’d like to know more about the mercs I play as and how they fit in the bigger picture of the game’s plot : )
Like for instance do any of the mercs have relationships with each other? Which ones are long-time friends, rivals, lovers, etc? This would be really cool stuff to know and really bring the characters to life even more. Do you realize how many fanarts and fanfics this would potentially incite? When your playerbase has even more reason to fall in love with the characters that is when you know your game is solid in the long run.
This is definitely one of the things League Of Legends did right with their champions, providing backstories and making each of them interesting characters in their own right, not just on the battlefield but also story-wise.
This stuff is good to have because not everybody who plays the game will be super hardcore competitive, so it’d be nice to have something else to keep the interest there : )
