I'm searching a plugins that generally improves the creature ,weather , NPC and player behaviour.
Creature: MMM? There are others, but that's the biggie.
Weather: Again, the biggie would be All Natural. But for something a little "lite-r", how about Enhanced Weather? Also nice. And there are others, as always...
NPC and player behaviour: In what way(s) do you mean? Could you be a little more specific, as to what you want changed (i.e., what bugs you about the vanilla game) ?
Could anyone post me link of any of such mods?
Not sure what mods you'll actually want in the end. Also, TES Nexus and Planet Elder Scrolls have search functions. As does Google. Oh, and this forum, though
that could be mightily improved upon.
edit: Not quick enough on the quick draw.
Again, dammit!
