Believe me, if there is a button in the game called "Kill him with a shotgun". The first time Eric comes in the game, I hit that button.
But for now to day Aleksey90 said:
" where the final choice of the player on the content will already take place - to give Lisa to Eric or protect her. But even before this point, the player will have many opportunities to arrange Eric problems, if necessary."
and
In the past, Aleksey90 had answered this as follows: It is the choice of the players to give any of the characters to Eric or stand in front of him ,except Ann. And we know Aleksey90 doesn't like Eric.
so
in the path to enmity with Eric. if there is a way in the game that Eric can not step beyond Ann. And the main character can completely stop him in front of others, this can be a more acceptable story for some players than other storylines. In this case, Eric's long presence in the game can only increase the challenge of the game. This is the main reason for choosing the game instead of other options. Otherwise we can watch the movie.
(No matter how long and hard this effort is, it will only add to the appeal of the game).
