In 2001, Pierre-Alexandre Garneau — then a recent computer science graduate in Québec City looking for work in the industry — wrote what became one of Game Developer’s most durable design essays. His framing is deliberately modest: nobody can define what fun is, so stop trying and instead enumerate the kinds of activities that reliably entertain people.
The fourteen forms, in his (explicitly unordered) list:
- Beauty — that which pleases the senses; drives the player forward toward the next beautiful place
- Immersion — inhabiting an environment different from your own; games get active participation where film only gets passive
- Intellectual problem solving — rules, setting, goal; strongest when problems have many solutions rather than one trick
- Competition — proving superiority, against others or against your own record
- Social interaction — the mere presence of other humans; beating a person is fun partly because the other person minds losing
- Comedy — pervasive in every other medium, strangely rare in games since the adventure-game era
- Thrill of danger — physical danger can’t be simulated, so raise the stakes instead
- Physical activity — real exertion, mostly confined to arcades
- Love — romance, affection, admiration; near-absent in Western games
- Creation — making exist what did not; SimCity, The Sims, and the entire unpaid mod scene as evidence
- Power — accumulating strength; the default motivator of most games
- Discovery — new places, weapons, and above all non-obvious tricks like the rocket jump
- Advancement and completion — going forward, and finally finishing
- Application of a skill — using ability in a difficult setting, where difficulty is the point
Several sub-arguments are more interesting than the list itself.
On competition, he argues for rubber-banding long before the term was standard: avoid “the rich get richer,” make the game generous to losers so catching up stays possible, and in single-player let the player win but make them work for it.
On problem solving, his preference is explicit — “finding the trick” is less rewarding than finding a personal solution that differs from other players'.
On comedy and love, he is blunt about the gap: films, books, and songs run on both, games mostly abandoned them after the point-and-click era. His suggested fix for love is unusually practical — have a character in the game acknowledge the player’s skill after a hard section, which is a cheap replayability lever.
On advancement, he derives a rule worth stealing: since advancing is fun, if a game isn’t fun on its own, making it easier at least makes it less bad. And short, highly replayable games are fun but rare.
The closing caveat is the part most summaries drop. The list is a tool, not a recipe: a game using all fourteen forms would be a confusing mess, one using only a single form would feel thin. Balance is the whole point — and the list exists so a designer can audit which features actually contribute fun and which are just there.
Six years before release, this is the essay that most of the modern “player motivation” model literature is re-deriving with worse writing and stronger branding.
