I saw this mod - Empire Wasteland.
https://www.nexusmods.com/newvegas/mods/53343

But, i read about many bugs. So - did any1 play this mod and is it safe to play after all??

In short: yes, this mod is save.

But this depends on how many mods you have already installed.
If you are having no troubles right now - go ahead and try it.
But if your game suffers from any problem (and i really mean ANY problem, even the smallest one) than dont even bother yourself with downloading. This mod is unpolished and unstable.

Anyway, dont forget to backup all your savegames. Just in case.

P.S:Sorry for bad english, i am just simple russian bear on unicycle, товарищ.
