…unless it’s Fallout 4 for $42.14:
While my parsimony is well-established, sometimes you just have to spend more money to spend less, you know? It’s Bethesda, I already know there will be crippling, horrible bugs on Day 1 and likely heading into Day 14. It is known.
…but I also know myself. Even if by some miracle I avoid spoilers (assuming there are story elements worth spoiling), I know that every other game I play during Fallout 4’s release to distract me from having not purchased it will necessarily be diminished. “I could be playing Fallout 4 right now.” “Am I having more fun than I would playing Fallout 4?” Thus, to me, in certain specific situations, not preordering will end up costing me more: either by breaking down and purchasing at full price, or by losing the value of fun from an already purchased game. So not taking them up on this deal is like robbing Peter to pay Paul.
Or maybe I just think ~$40 is a fair-enough price for this game and I don’t expect to be able to pay that amount two months after release.
…or maybe both. Yeah, probably both reasons.
