Fallout 3 mods?

So i picked up fallout 3 from the steam sale and i just got around to playing it. I installed the NMC texture mod, tweaked some setting with sweetfx but I really feel that the game lacks when it comes to the sky. Are there any good mods/tweaks that enhances the skies? 
Also any other mods would be great!

 

Thanks 

Have you tried Fellout?  Definitely a must have imo.

Gonna try that right now! 

I have had so many problems with running fallout 3 on my PC I haven't touched it in months and almost forgot about it.  I have tried everything ive found on forums and nothing has worked.  What rig are you running this game on and are you crashing?

(im running win 7, 64 bit)
