I am divided on which one I find worse; Fallout 3, Fallout 4, FOBOS. I have not played Fallout 76 so I can't judge that but it is very unlikely I will play it.
Fallout Tactics IMO is above all these three but not as good as Fallout 1 and 2, and Fallout New Vegas.
Technically I should find 3 and 4 better but FOBOS I can actually start and finish while I can't be bothered with Fallout 3 any more and I am really not interested in finishing Fallout 4 and its genuine DLCs because I am just so bored with these two.
Even if I would like to play the Pitt again or Point Lookout I just can't be bothered with going through Fallout 3's campaign first, even if I put in all kinds of mods. (which I did and the game would not even start any more)
It is dumb but I would rather see FOBOS remade but fixing all the lore consistencies, rewrite the dialogue, and improve the gameplay than play a remastered Fallout 3.
Years ago when I played Shadowgrounds I became interested in the idea of a TC with a campaign following up on Fallout Tactics, or one set around the time of FNV with the player assuming the role of a Ranger in NCR territory, facing bandits, remnants of the Unity, the BOS (the BOS-NCR war) with which the player could make some peace with, and having to prevent a military coup by NCR hardliners using weapons retrieved from Area 51.
It wouldn't be a RPG anything like Fallout 1 and 2 or an action rpg like FNV, just an action-adventure with upgrades.
