Can we make an exception in my case? All my reviews are over a decade old and kind of embarrassing (as I'm sure many here would agree), and I really wouldn't have a problem with them getting replaced.
It used to be that way and then you were upset that people were editing your reviews and/or replacing it and keeping some for theirs, etc. It makes much more sense simply to keep the existing restrictions and remove offending reviews entirely so they can be replaced anew.
However, I don't think it's a good idea to remove them ALL. Many of them are just fine. There was a drive to remove some of your worst ones some time ago. At that time a number of people also said they liked your reviews and removing them all was not a good idea.
So, maybe just point out the ones that you think still should be removed and we can do that?
However, should Game Reviews function like Romhack Reviews where only the authors (i.e. no staff access to it like romhack reviews) can solely edit them?
Game reviews are front facing on translation and game pages. Staff needs the ability to be able to edit these to fix typos or other problems with them. I don't see what the problem is allow staff to be able to edit these if necessary. It's a rare occurrence.
