Really good. Yeah, I agree. If there's nothing there at all, might as well put something in. Not too sure about metadata but I'd definitely notice if an image was bad or doesn't fit the criteria at all.
On another note, I strongly believe if a game is going to use its Japanese name it should display its Japanese Box Art. Plus it wouldn't be a bad idea to have separate Ids for different regions since they are technically different games.
I'm not sure if it's appropriate to put this here but I thought it would be a good idea.
