I do, always play vanila.

I usually play vannilla but I have found some interesing mods. I will try polyamorous mod and busty mod :D

Mods can mostly be divided between small improvements or big overhauls (plus expanding aspects like additional / re-balanced classes, weapons, challenge maps and such).

That's the one advantage in terms of unofficial content the Pc (this) version has over the Console versions is expanding the game once the player is comfortable with vanilla.

Yes, I love the vanilla game. I spent many years only playing vanilla. However, it was a great awakening when I finally decided to try some mods. I switch between different batches of mods and vanilla frequently.
