Fallout 4 is not an RPG by my standards.  It is a looter/shooter that tries, and fails, as an RPG.  Yes it is an open world, and yes there are multiple ways to get from Vault 111 to the end game, but every single one of these routes is determined by Bethesda, not by the PC.  Just because you can select your PC's gender and looks, choose your SPECIAL stats to "build" skills, and say "yes/no/more info please" on the convo wheel. .. (sigh) not an RPG - just some RPG elements.

You are still forced to be the parent of Shaun, the Sole Survivor,  rescue the lame npc's with Garvey and then build them a home and babysit them. These  people should all be dead, since they are too stupid to even pick their own bed, and whine that they are starving while staring at  a field full of tatos, corn, carrots, melons, mutfruit trees, etc (even more heavy sighing by me).

OK, I know there are a lot of limitations when developing a video game, and RPG's still need some structure, through a story with a beginning, middle, and ending.  It is the forced "Sole Survivor must rescue Shaun" part that yanks me out of the role play.

I can not change these "problems" with FO4. I would have to make a new video game from scratch... nope, not gonna happen. no skills in that area.

All I can do is find ways to give myself more Role Play freedom within the confines of the game.  Until now, I have used a multitude of mods by others to help me out, and that almost works.

But.... the majority of these mods do not provide any significant motivation for the PC to go off adventuring and abandon Shaun to his fate!

The underlined part above ... I think I can do something about that.  We will see.
