Seasonal creative calendars for games
CPM inflation, cultural moments and budget cycles repeat every year. Building a twelve-month creative and budget calendar instead of reacting each quarter.
Every studio relearns the same lesson every autumn. Planning that starts a few weeks ahead of a seasonal spike starts too late, because production lead time doesn't compress to fit a calendar deadline, and neither do briefing cycles or network review queues. Studios that treat Q4 as a known recurring event rather than a recurring surprise walk into it with a stronger slate. Every year, without fail.
The recurring pattern worth planning around
A handful of periods repeat with enough consistency to plan against directly.
Q4 runs from roughly October through December and brings sustained CPM inflation, as retail and e-commerce budgets compete for the same inventory alongside entertainment. This year the pattern compounds. Take-Two has confirmed a marketing push for GTA 6 ahead of its scheduled November release, which drops an unusually large, mobile-adjacent demand spike into an already crowded auction.
January is the reset. Broader advertiser budgets refresh, consumer intent for new habits including new apps genuinely rises, and the month turns into one of the more efficient windows of the year for volume-driven UA, provided the creative is ready in time to use it.
Ramadan and the Eid period that follows shift usage patterns and ad receptivity sharply across large Muslim-majority markets for several weeks, which calls for a media plan and creative built for the period rather than a paused campaign. Lunar New Year does something narrower: it concentrates spend and cultural relevance across East Asian markets inside a short, fixed window. Back-to-school in August and September shifts available attention in several Western markets, modestly but really. Then summer, which most teams write off: July and parts of August bring a genuine dip in engagement and in CPMs across several markets as attention moves outdoors, and that cheaper window rewards testing rather than neglect.
Building the calendar backward from production lead time
Most teams build the calendar forward from the event date. The useful version runs backward from how long creative production actually takes. Say the Q4 slate has to be live by early October so nothing launches cold into peak CPMs, and full video production plus network review takes six to eight weeks: briefing starts in August, not September.
Work that backward across all five or six recurring moments in a year and you end up with a handful of hard deadlines. Briefing dates, not launch dates. A creative team can plan a year of capacity against those instead of discovering each one a month late.
Budget implications, not just creative ones
The calendar isn't only a production schedule. Q4 CPM inflation means the same budget buys fewer impressions, which argues for one of two moves: front-load spend into November ahead of the steepest part of the curve, or accept a lower volume target for the period and protect efficiency instead.
January argues the other way. Lower CPMs and higher intent make it, often enough, the highest-efficiency month of the year to spend aggressively, and a studio that has emptied its budget on a Q4 push has nothing left for the window that would have used it best.
What a twelve-month version actually contains
A useful calendar is short. Five or six named windows. For each one: a briefing deadline, a launch deadline, the markets it actually applies to, and a rough budget-shift note saying more here, less there. Ramadan and Lunar New Year are regionally specific, so neither needs a global creative refresh.
The calendar doesn't have to forecast exact CPMs or commit hard numbers a year out. It has to exist, get reviewed each quarter, and stop a Q4 that the whole industry can see coming from January onward from turning into a fire drill.
A calendar that lives in one person's planning document rarely survives a team reorganisation or a change of creative lead. Most of the seasonal scrambles that still happen at studios with a perfectly reasonable plan on paper trace back to exactly that: the plan sat in one head or one spreadsheet instead of in a shared document that media buying and creative production both check against their own timelines.
So give it two owners, whoever runs media buying and whoever runs creative production, with a standing quarterly review slot on both calendars. Small governance step. It decides whether the plan built this year still gets used two years from now, long after the person who first wrote it has moved to another role or another studio entirely.
