What are oblivion mods

its where some computer nerd hacks into the game , making their own races, weapons and horses and stuff.
fun to play with but ruins game quality and ruins story,
basically permanent cheats


Actually i'd have to disagree, some mods make oblivion better than it ever could have been, like Deadly Arts, and deserts of elswyr aquinna (not sure bout the name) and what about morroblivion (adds all or morrowind to the oblivion world but needs the morrowind disk) that's not ruining the game its just making it better, but SOME mods are almost worse than cheating, anyway these arent permanent they can easily be removed,,, im looking forward to the completion of MERP, (its a middle earth mod which is around 7 times larger than tamriel)

some mods are cheap but some add more depth to the game
