Then you are not Bill.
But honestly, I can't tell you what you can/cannot do with your money. If you are enjoying the game, then more power to you, and money was well spent.
However, incidents like last year's Arkham Knight fiasco really put the whole idea of pre ordering under the spotlight. The developers were not forthcoming about the fact that the PC port was being handled by a different studio, and we all know how that turned out. So what I am saying is that it is going to be a gamble when you are pre ordering anything.
