If you're patient, hexer and other people are working on Fallout : Yesterday.
I mean, if you're gonna be that patient, you might as well wait/pray for the likes of
F4NV or Cascadia. Again, it comes down to
what the OP liked about New Vegas.
I don't know about you, but I'm glad an alternative to Bethesda's "Fallout" 3 is in the works. Unlike Interplay's Fallout Online / Project 13, I'm sincerely interested in playing Van Buren (I know hexer isn't an Interplay developer, but like killap, he's developing something based on documents of developers).
If you want to rush things, you can do generous donations to his Patreon page. Feel free to do so.
But I would rather he and his team take their time, and make something truly awesome. Like Fallout 1.5, which took the czech developers many years to finish, but it was well worth the wait.
I'm a Berserk reader, I'm used to waiting for things.
