World building is a central tenet of tabletop gaming, and it certainly illuminates the sheer immensity involved in a living planet. Vast continents spanning climates and cultures await those willing to explore, and one need look no further than our real-world example for an education. Worlds are impressively large. Tropical islands concealing pirates, frozen tundra home to deadly, cold-adapted wildlife; inhabited worlds have a bit of everything. Physical geography is just the beginning of an endless mosaic of possibilities.
An eastern religion storms westward, brought by the sword. Rats from their ships bring a deadly plague to foreign ports, a perfect storm depending on where someone just happens to be standing when it happens. Worlds are massive, and airplanes haven't done enough to shorten the distance. Now contemplate the vast universe in a spacefaring scenario complete with occupied planets as big as our own. Individual worlds become a pitstop for wandering spacecraft, reduced to mere blips on some rock's vast surface...
It's a matter of shifting scale, where the void of space becomes a new world and individual planets its towns and far-flung villages. An unavoidable accommodation, although not outrageous or unsound as spacefaring types can only experience the specific locations their vessels happen to land upon. Laziness is a potential risk, however, with simple one-world governments and geographies that defy latitude and spheres. For referees and writers, this is a time-saving mechanism that actively serves to diminish these worlds.
The best way to avoid this trap is to formulate some idea of a planet's situation even as the spacefarers only experience their small portion. Perhaps open (and bloody) war rages between continents, with impacts to the tiny spaceport the characters encounter, uncovered when the party converses with the locals. A few scribbled notes are normally enough for narrative purposes, although it helps to have a system. Our Planetary Worksheets designed for the Blood of Pangea: Retrospace RPG are free for the curious...
Sketch a quick surface reference, identify its major regions complete with climate, resources, and relevant heads of state, plus whatever additional details, including catastrophic wars, perhaps driven by plagues or natural disasters, define the place. Establish a checklist, using our planetary worksheets when not a better homebrew alternative to flesh out convincing worlds on nothing larger than a regular index card. Even the smallest of planets is enormous and deserves to be treated as such, and the briefest of sojourns will benefit.
