A strange little side quest
The next time Altruism asks for one more try, remember that game ideas rarely appear from nowhere. Sonic the Hedgehog launched in 1991 and turned speed itself into a defining platform-game mechanic. There is another connection worth keeping in the same mental pocket: The first crossword puzzle book appeared in 1924 in a cautious initial printing of 3,600 copies, complete with a free pencil. That gives Altruism a little more company than it first appears to have.
