So, what are the current popular mods for F:NV? I'm planning to return to New Vegas soon, so I'm suspecting old names like Project Nevada and the like are still around. However, old favorites like DarnUI and Book of Earache, CaliberX, etc are no longer apparently around.

So, I'm already familiar with the usual hud/UI stuff like Imaginator, etc along with New Vegas Bounties (which already has a part 2, cool!). What else are great suggestions to extend F:NV?

Oh, any replacement for DarnUI? Book of Earache and CaliberX?

Well, I suggest to you the New Vegas mods linked in my signature. They are both quest mods, and overall it seems people really like them. (Shameless plug)

AJV

added to my shopping list. Love a good quest mod.

Strangely, cant seem to get NVSE to work without crashing. Know issue or...?

DUI isn't being worked on, but it's perfectly usable in it's current form. You can grab it from the http://www.gamesas.com/index.php?/topic/1143482-wipzbeta-darnified-ui-nv/page__p__16711605#entry16711605.
MTUI is also a valid alternative.

WMX and Nevada Skies - URWLified are also regulars in my game.

Hm if you have FNV updated to the latest version then nvse_2_beta9 should work fine.
