My friend explained to me difference between Fallout 3 and Fallout 4. Now I can understand all the RPG players who had problem with Fallout 4. I guess I will never play Fallout 3 because Bethesda didn't bother to make playable GOTTy edition for Windows 7, but I'm glad I know now what is worse for RPG in Fallout 4. I couldn't understand those critics at all, they never said any arguments I could understand.
In Fallout 3 you managed more your character by skills. It wasn't only about some addition to perks, but it made progress visible to you, so you had the feeling that your character is developing, not just by levelling up. Also you really couldn't use skills you didn't trained, so you were not grey person, who knows everything a little and is getting better by acquiring better weapons/armors, but you had to pick only some skills and play the game with that, esp. in combat.
Also there was important Karma system for stealing/killing, that made you good/bad guy, so that feature, that would some players want in Fallout 4, it was there actually.
In Fallout 4 you are almost the same the whole game, you don't see much difference when you level up, because perks doesn't mean that much in progress - only once per a lot of levels, but in the meantime, it is just boring grey character. They took away the RPG element of roleplaying the good/bad guy.
That is also what makes Fallout 4 more FPS than RPG.
Also you cannot really roleplay a wastelander without survival mode with food/sickness, so there is no point to use those empty shelters or play the game without quests.
Also - why is the new dialogue wheel worse - because it does limit even the quest designer to have always 4 option, but quite often in games is needed less or more than 4, so it does limit that freedom of choices in this way.
So I believe, those changes were worse for RPG. Question is if Bethesda wants to make RPG games in future, after I saw those radiant quests and all the changes to simple shooter action game.
