True, if and when I ever get around to replaying things that could be a problem (although the industry has seen to remaking everything I cared about, sometimes poorly, but that's another problem).
Another shout-out to the nerds running retroachevements though because they thought it that; they have an encore mode that let's you redo achievements. Although honestly you could just make a second account, that stuff is for emulated content anyway and it's not like it's DRMed, haha.
