i played a bit of fallout 4, but i dont really understand the hype that was around it. its a loading screen simulator with an awful city repair element slapped on top.
not a huge fan :/
it sucks... i really enjoyed all of the previous fallouts i played (FO1, FO2, FO:BoS, FO3) and expected something better.
You're right, Fallout Shelter for mobile and I guess I forgot about 76. I was thinking "mainline" Fallouts.
New Vegas is an amazing game with an even more amazing modding scene. Absolutely recommend you getting to it down the line, it's a bit closer to the OG Fallouts than the Bethesda ones. Superb DLCs as well, all of them really good.
