Well, after a while i stepped (pun intended) on the S.T.E.P. guide and i decided to give it a try.
I'vce downloaded like 200 mods and i'm only half the way of installing them, and i'm like extremely slow/careful since given the increadible amount of textures/resources i have so much fear of screwing everything
When i've finally finished, i'll post results (either screenshots of the game or my rig on fire, depending on final results).
