True to that. I personally don't know what is Mary Sue but roughly I think it means an unrealistically over-powered protagonist
. We, the players did not witnessed the character development of
Zaton because pretty much we start in the middle and the game just established that the MC is a very competent Desert Stalker.
However, we the players will also realized ( by playing the game ) that the MC has boundaries that even he cannot cross yet, for example how he deals with
Queen Merneith (
Zetan ) and
Fangs ( the
Mutants ). Also, if the player did not unlock the
Raiders faction, then the MC is not able to take control of the highway settlement without the support of the
Raiders i.e. he is not able to oust the General on his own. In short, there are specific examples in this game that counters the opinion that MC is a Mary Sue.
Perhaps, there are specific instances where the MC appears to be invincible but none that I can remember. I don't even remember that there were so many battles or fights in this game
. Well, nothing that feels supernatural or unfitting for fiction at least. But yeah, the story is not leaning towards realism much, but at least it tries to make most of it, believable.
In the end, it is not simple or easy to get the balance right. If the game with a weak MC and the game is supposed to be about his/her character growth, some people will not like it and immediately become the discussion about cuck, beta and what not
. On the other hand, if the game features a Mary Sue MC, then some other people will not like it because the MC just basically conquers everything without facing any hurdles. It becomes an online shopping experience, add items to cart, checkout, and wait for delivery.
