I have completed the Game. I now wish to start over, but this time, find as many funky weapons, all cache-rocks, etc., as possible, which I did not, or could not, do the first time. BUT, when I restart the game, the number of saves continues to increase from the previous total when I finished the game (just over 550). So, how may I reset the Save-Count to Zero on a Fresh Start with a New Character? Thanks!

zip all the files in your documents\My Games\FalloutNV\Saves folder, then delete your save files

Thank you. I'd tried that earlier, but must've messed something up, as the counter continued to iterate. This time there was no problem. Thanks for the fast response. Off to the Wasteland!

no problem "enjoy your stay"
