Just remembered something else I wanted to suggest. I would hope to get something like a check box for games I have finished. I have been through many sites where I used to do that, and well, Gamefaqs doesn't make it easy so that is like a month long process, and all the other sites/facebook apps I've used have all gone to crap because they just made bad updates, and then no update.
What I hope to do is tag games that I have finished (I'll use my own definition of finished thank you very much) so that I know what I have beaten and what I still have left to play, as my RPGs alone are the reason I may never finish all my games I keep buying. I guess an example (no so much visually) would be myanime list (
