I played it summer of 2005, the same year I binged Douglas Adams' complete non-HHG works (including 'Last Chance to See' on CD-ROM and the interactive fiction game, 'Bureaucracy').
Afterlife is wonderfully fun and satisfying to experience to completion for the first time, and what it might lack in replayability it more than makes up for with humor and design.
I still play once a year. But now I can reach full omnibulges and love domes in less than an hour. But I remember spending months to survive until I discovered the cheat code (btw if you use too much, it triggers something that I can’t remember, it can mess up the game as a punishment).
The I figured out to let the planet evolve and grow it’s population because then, your afterlife has high demand thus more money, that detail solves the hardest part of the game!
The other insight which came much much later, the better capacity per area is given by the top 2x2 and 4x4 multi color. 3x3 top buildings are badass looking but they offer smaller max capacity for souls, we are aiming in reaching 1 billion souls using the least amount of area so you always have free space to build as demand explode.
