@sirber I understand. They will go back to the roots with 5 for sure, but you know Bethesda, they aren't rushing it.😬I reckon itll be several years before we see another single player Fallout because they're doing Elder Scrolls now.
However, have you tried 76 again recently? It's REALLY changed and there's several neat storylines akin to the main games. You can experience most everything solo just like a normal Fallout game. Though, it IS much easier to play multiplayer because of the trading aspect, but it's not required and I found it really enjoyable.
