I really wanted to be in on it from the beginning to be along for the entire story as it develops, and ooh boy was that a mistake. Haven't played it since January and looking at the progress since then there isn't really much to draw me back in.
Bethesda RPGs don't really "end". Fallout 4 had a little slideshow when you finished the main quest but no credits roll. Then you're dumped right back into the game.
