so if i load my save game from xbox,and play on my friends pc,could i download mods and bring them back to 360?i know this is kinda a noob question but i am a noob to pc gaming

In a word: no.
That's one major gimp for console players, I feel for you guys.

ah well thanks,had to try....damn i didn't want anything major like the Blackreach railroad.just customization of npc's,buying a follower a horse,and the mod where you can relocate npc's to new houses.

Nope, sorry.
