Fallout 4 - Roleplaying Game?

While it does have a great deal of role-playing mechanics, it's categorization as an actual RPG is up for debate.
Level up - check
Skills - check
Exploration - check
Effect on the world - no check

While giving plenty of choices for character developement, Fallout 4's character choices have little to no effect on the world.

Is it really an RPG? In this writer's opinion...no. It's a character building game. Not a true RPG in the sense that your character's choices don't really seem to effect the world or how the world responds to you.

To quote (and agree):"65 hours into this game, finished on Institute playthru and going back now as another faction. I have noticed that in almost every dialogue choice, what I choose doesn't matter. Either I say no, and the quest is halted, or I say yes in 3 or 4 different ways. No matter how I say it -- sarcastically, genuinely, etc., end result is the same: I go running off to do the questgiver's bidding. I have yet to find meaningful choices outside of the faction-divergence choice. Small side quest choices have no lasting impact other than a few random NPC commentary as I run by. They all wrap up nicely into a little compartment when they're finished."
