I discovered the benefit of 'deleting' stuff last summer when I moved to a new apartment. If it has been sitting in your closet untouched for 12 years, then you almost certainly don't need to keep it. I saved some things like that, of course, because of the sentimental value (HS yearbooks and mementos). But there was plenty of useless junk just taking up space that I didn't want to have to move. (And carry up 2 flights of stairs, since I they only had a 3rd floor unit available in the complex I wanted to move into.)
doesnt have to be a stat like hp or mana or Heroics...it could be something passive to add in some fashion
