Halo: MCC was the first game I ever preordered. That was only because it is my favourite game series ever (worth paying £45/$60 for) , and because I knew exactly what to expect (i.e, reviews were going to be worthless anyway).
The way I see it:
- if you preorder you pay full price.
- if you preorder, you dont get the benefit of reviews.
- if you dont preorder, the price of the game will drop in the coming months, so you can save a decent ammount of money for your patience.
