Without this discount, people should hopefully start to relies that pre-ordering games is a really stupid idea. Pre-ordering games is stupid for a variety of reason, including;
1. Games often go on sale within months of launch, mean you can often get a better deal by waiting.
2. If you pre-order, you don’t know how good the game is as there are no reviews.
3. By pre-ordering, you are telling game developers that you will buy their game no matter how well it is made.
