Quick Summary

Why Steam Won
- Critical mass: Being first to digital distribution created a self-reinforcing network effect — more players → more developers → more players.
- Steam Workshop: Built-in modding support with one-click subscription.
- Greenlight → Steam Direct: Evolved from community voting to direct paid submission ($100 fee).
- Early Access: Pioneered Early Access as a legitimate release model.
- Community features: Reviews, forums, trading cards, achievements — a complete social layer.
The “Steam Tax” Criticism
Steam’s 30% cut (reduced for high-grossing titles) is frequently criticized as the “Steam Tax” — a significant cost for developers. This criticism gave rise to competing platforms like Epic Games Store offering 88% to developers.
