Neither Deltarune or Silksong could be preordered so everyone was zerg rushing the stores at the same time.
Note to clouders, they could spend on pre-warmed autoscaler pools, but a corporation that spends a single dollar of revenue more than necessary to make the sale is violating its duty to shareholders, and total gross launch revenue will be the same whether they do or not, so they won’t, even though they could.
Note to game developers, for this exact reason you should be demanding launch month bonus targets rather than day or week; any less and you’re being knowingly ripped off by business execs.
Sometimes, the idea hits so hard that you don't even need the time investment. Notch got Minecraft from version alpha to version 1 in 2 years. That one was lightning in a bottle; unlikely to be reproducible consistently.
