Journey to Vault 79 - Full Playthrough
Journey to Vault 79 is a buggy, awkwardly paced mod set in mostly barren environments that are probably too large to justify themselves.
For some reason, I like it anyway.
Sometimes you just want to shoot some dudes and not worry about things like "narrative" or being the bestest most high quality mod ever.
I personally have a fascination with mods liek this that just "don't care." There's a certain kind of immensely enjoyable product that can only be achieved with that mindset.
It helps that the bugs aren't too frustrating to deal with (at least if you have some Geck/Console literacy) and some of the environments are decently fun to navigate and fight through.
