I’d wish to make sport, the place one half is managing planet (constructing cities, factories, roads, and so forth.) however I’d wish to keep away from 3D – solely what I would like is sweet 2nd. But if I characterize planet’s floor as a grid, it is going to be unusual to maneuver close to poles (if I am going up, I will not seem within the backside of the map, however within the prime – solely in several place) and it is going to be onerous to have good terrain (poles can be stretched). Do you will have any concepts how to try this?

Games shouldn’t be practical, you may all the time minimize some corners if it makes the sport higher. Take a take a look at Ascendancy for instance:
You can loop the 2D terrain from left to proper and from backside to prime. Like a Civilization map does.
Another possibility can be to make “unwalkable” polar caps, like we now have right here on Earth 😉 They will conceal the areas of stretched grid.

Section 2 of this paper has some attention-grabbing notes on hierarchical triangle fashions, however you may discover extra instantly helpful materials taking a look at geodesic grids. You want to provide the connectivity data, however that may get you to an excellent approximation of a sphere.
This paper additionally has some attention-grabbing concepts.
As Krom identified, you actually can setup your individual system for connections, permitting for colonization of bizarre extra-dimensional areas on the weirdest, or less complicated constructions comparable to a Halo-ish ring world.

The “correct” solution to characterize a planet’s floor with none particular therapy of the poles or some other excessive factors is a triangulated irregular community. From there, you should utilize any of the standard geographical map projections to characterize no matter a part of the floor you need as a 2D map.
