1) I would rather prefer a snow season with proper athmosphere! Considering that navezgane is located near desert zones - there must not be any signs of snow as a permanent event! Currently its has even less sence because temperature mechanic was removed for rework!
Assuming temperature mechanic returns, that addresses two concerns (really the same).
There are both hot and cold deserts and the Arizona valley is surrounded by mountains. Mountains are high, temperatures go low. Popular ski destinations like Flagstaff Snowbowl and Sunrise Park Resort offer winter sports opportunities near Phoenix.
I will give you the seasonal aspect, but in a game as short as 7d2d, it does not really fit.
2) Burnt biome is a cringe, in reallity its just burnt place with no plants at all (in 7 days its still has plants somehow which is dumb)! Has cringe gamma which looks bad! Also isnt a permanent event and is artiffical itself!
The burnt biome is modeled as a recent burn. Due to the 7d2d lore, we don't know how long ago it was to have burned.
Agreed, it does not look very nice, nor does look like a burnt biome several months after a fire where new green growth abounds.
3) Wasteland is alvery strange and cringe nowadays (in old alphas it was radiated and required hazmat suit which was logic - later was removed), has cringe stone surface which is very dumb considering that after nuclear bombing (and navezgane is far away from the explosion center) - dirt still remains on its place! Wasteland must not be a small biome but instead, cover all maps smaller than 10-12K (within the conventions of 7 days of course) (also all buildings (especially their windows) must be heavilly damaged from nuclear shockwave which i dont see)! Nice biome for challange only (like wasteland only map if u want to simulate fallout)! Never had need of it
As noted you never needed a Hazmat suit for the wasteland.
Your interpretation of the lore, is that Navesgane was far away from the epicenter of the nuclear bomb, yet is missing broken windows from the shock wave. Those two circumstances almost mutually exclude each other.
4) Desert biome - a difficult location with very low amount of plants (unlike 7 days)! Desert geography is well made on navezgane map! Nice biome for challanges! Never had a need for it
Your perception of a desert biome is not necessarily accurate. Hot deserts are home to a wide range of species: 500 species of plants, 70 species of mammals, 300 species of birds, 100 species of reptiles and many species of spiders and scorpions.
So for me, forest is the only natural and organic biome (others are bad made and lack of athmosphere)! Sadly lacks proper ecosystem and wildlife
I get the sense that you have avoided other biomes becasue they don't meet your expections of what they should be. I suggest your "expectations" are the issue, not the biomes and are not supstantiated. The forest, desert, and snow biomes are the most "realistic", the burnt and wasteland less so. Luckily, we as players get to choose where we live in the game, based on any criteria we so choose.
