Post
Give away the first episode free, charge for the rest. The original free-to-play model ran on floppy disks and trust.
Before digital distribution, shareware was the internet's predecessor for game distribution. Developers would release the first episode or chapter of a game for free, encouraging players to copy and share it freely. If you wanted the rest, you'd mail-order the full version. id Software perfected this model with Commander Keen (1990), Wolfenstein 3D (1992), and Doom (1993). Apogee Software (later 3D Realms) built an entire publishing empire around it. The model worked because the free portion was genuinely good (a real demo, not a crippled teaser) and the sharing mechanism turned every player into an unpaid marketing department.
Example
Doom (1993) was shared across BBSes, floppy disks, and university networks so aggressively that id Software estimated 15 million people played the free shareware episode. Only a fraction paid for the full game, but that fraction still made id Software millions and created one of gaming's biggest franchises.
Why it matters
Shareware pioneered the 'give it away, then monetize' model that free-to-play games would later perfect. It proved that reducing friction to try a game was more valuable than controlling every copy, a lesson that took the rest of the industry decades to learn.
