When I said "if only there were a way," it was tongue in cheek. However, there is the possibility that the games you know list was implemented in some unfortunate way that you can't actually remove elements.
Out of curiosity, I did a little digging, and apparently some databases include table types that are append-only.
I get that sometimes you want an object to be immutable, and this games you know list is quasi-immutable (hemi-immutable?), but I don't know why you'd want that.
