my humble advice. If you need to record the original price or state of unsealed games, you can add it on some paper inside the case. But I strongly advise to remove those stickers including those case sealing stickers. That is because over time the glue will start curing and it will react with plastic surface (that would leave a permanent plastic deformation under it (as if the plastic had sunk a little bit or stretched where the sticker was). And worse yet, the glue can be difficult to remove. And that is way more the case if the sticker is on those fancy paper slips (like the House of the Dead game).
