it's definitely an rpg still, but the rpg mechanics that previously existed have definitely been significantly simplified
it's not necessarily a bad thing, but i can understand being upset about it. the new approach is definitely a lot easier to teach and likely a lot more intuitive to most players. from a design perspective it makes sense to try to create mechanics that are easy to teach and work with. the important part is if those mechanics actually produce compelling gameplay and i've yet to determine for myself how fallout 4 compares to previous games in that regard
