enter image description here (Up is north) Color key:

Light grey-snowy area, somewhat mountainous

Dark grey-snowy area, extremely mountainous

Dark Blue-somewhat cold hill area

Orange-somewhat moumtainous. Not too cold.

Light green-mid temperatured plains area

Purple-temperate forest.

Light Blue-metro area



White-wasteland from nuclear warfare in past

Red-area where surrounding biomes have drifted in, but is mainly a metropolis

Pink-coastal area with forest in it's eastern portion

The brown line is the equator. The key in the image shows how long a mile is. The orange and grey areas are a mountain range that spans all across the northern border of my "kingdom". Other than that, the rest of the land is relatively flat. An ocean is to the west. South, east, and north is all unexplored.

As my title says, is this set up realistic. My main concern is that the different biomes are too close. The planet is sames as earth, simular star, but a smaller moon.

    $\begingroup$ Please don't change your question to invalidate existing answers. You showed us one map, people answered on how realistic the biomes on that map were. By updating the map you are making their answers and the effort they put into answering them invalid. $\endgroup$

    $\begingroup$ Sitting right on the equator, jungle is the dominant biome. With that size you can have more than 1 or 2. $\endgroup$

This setup isn't too bad (there are plenty of video games out there with less realistic biome configurations than this), but there are still a few things I find odd.

1. The placement of your city/cities

As I understand it, the light blue biome is all one city, and the red biome is either a second city or an extension of the light blue city. However, looking at the surrounding biomes (mountains on two sides, jungles and forests on the other two), this doesn't seem like a very logical place for such a large city to have developed. Especially when there's a nice coastal area only a dozen miles to the west, that seems much more suitable. I'd move your city over there, next to the ocean, and add a large port and/or dockyard on the coastline.

2. A jungle next to a desert

Your intuition is correct here. These biomes are too close, and it would break my immersion as a gamer to go straight from a jungle into a desert. You're better off placing your desert near your mountains; mountains act as a rain shield, stopping water from reaching the desert and leading to its arid climate. You'll also want at least one river flowing from your mountains to the sea (preferably, through your city).

3. The nuclear wasteland

This is right in the middle of your mountain range. It seems like a very odd target for a nuclear strike. I don't see why this particular area would have been nuked, and not the large city/cities only a few miles away. At the very least, you'll want to explain it within the game's backstory.

4. Don't make the coast a straight line

I feel like this is an obvious one, and that the boundaries on your map are just rough examples that will be made more precise when you create the full version for the game, but I might as well note it anyway. Real coastlines curve and meander all over the place, and aren't ten-mile-long straight lines like you've drawn here. This question has a few tips for creating realistic coastlines, that may come in handy for you.

  • $\begingroup$ I like your answer! I have decided that the nuked area will be where an old city stood, and to move the mountains a little more north so that area doesn't look to be part of a mountain range. The desert will be where the red area splits the orange and grey area, and extend over a little south. The area where the desert is now will be part of the ocean to the West. I will come up for a place for a river. Also, the red area will be only the size of it's southern half, making it more realistic. Finally, I had already planned for a coastal city in the pink area. Thanks for the help!!! $\endgroup$ Commented Jul 28, 2017 at 16:44

  • $\begingroup$ @TheMattbat999 While it's absolutely your perogative to choose which answer to accept and when, it is generally recommended to wait at least a day before accepting an answer. Accepting an answer tells the community that you feel your question has been adequately answered; in doing so, you reduce the chances of getting further, even better answers. $\endgroup$

First of all, I'd consider the difference between "realistic" and "plausible".

Given the medium, you're already compromising on scale and so realism may be out of the question. But by aiming for "plausible" you look to satisfy some simpler criteria - primarily, does the structure of my world meet the expectations/assumptions of the player?

The first thing that jumps out at me is Jungle to Desert. That seems like a jarring transition to me. It's a meeting of two extremes - wet, dense with flora and fauna suddenly meeting dry and sparsely populated. I feel there should be some intermediary transition there.

Your other natural biomes are plausible enough - though you might want to consider the other end of your latitudinal scale - the north pole. Your cold areas seem to be cold due to altitude and that works, but it's hard to get a sense of the effect latitude will have.

I think you could probably revise your constructed biomes. Most metropolises (metropoles?) are either coastal, or on a major body of water, and require arable land to support food production, so consider where a city would firstly be situated by its settlers, and the factors that will promote continual growth.

In tandem with that, what was your wasteland before it was decimated? It would need to be something worth targeting - presumably another city, and so you ought to consider it's merits for prosperity too.

    $\begingroup$ Jungle/Desert is an extreme, I'll grant, but I think that if I had ultimate control over geological...stuff I could get the two to smoosh up against each other. E.g. if the desert was a desert because it was a salt barren (e.g. a dried sea), I could see it abutting a jungle with fairly close proximity (heck, the desert might actually be encroaching due to underground water flow bringing the salt over). It wouldn't be stable in perpetuity, but it would be plausible. That said, for a game world? I'd squeezes something in between them. $\endgroup$ Commented Jul 28, 2017 at 19:30
