The Digital Game Buyer's Economic Principles

The Double-Launcher Friction Cost

Even when games are bought on Steam, titles from Ubisoft or EA often boot their own thin client. Buying directly eliminates the dual-layer, but buying on Steam retains cloud synchronization, Deck Proton compatibility, and community controller templates.

The Voucher Code Threshold

Promotions like Ubisoft's UBI40, Epic's seasonal mega-coupons, or GOG wallet discounts only beat platform lock-in when the cash difference exceeds your personal friction tolerance (typically $3 to $5).

Backlog Cost Per Hour

A $5.99 game you play for 45 hours costs $0.13 per hour of enjoyment. If an incompatible launcher discourages you from launching it on your handheld, the effective cost per played hour skyrockets to infinity.
