You make fallout 4 seem quite interesting, I will have to check it out. I have a friend who plays new vegas quite a bit.
It seems you and I have similar interests in games, for example open world. I have to admit though, the npc's aren't that interesting in some of the games I play. I used to spend a lot of time in Empryion, but got burned out on it, now my friend has got me playing No Man's Sky, which is interesting. I like the base building, and stuff like that. I have dragonage, but not sure which one.... couldn't get into it either, but didn't really give it a good chance. I thought the Witcher games would be interesting, so I bought the latest one, but it is rather complicated when it comes to fighting, so I have not gone back to it.
As for ES:online, the graphics turned me off on that game. In Skyrim everything was big and seemed lifelike, in the online version it was small, and just didn't seem right.
