Differentiate the four lands from each other #11
Description
Each of the four lands should be different than the others, with bonuses and penalties. Additionally, there should be at least 2 creatures that are unique to the lands. This ensures that players can make themselves feel better by saying things like "I knew we should have gone to the X lands", and increases replayability.
The snow lands have an emphasis on frequent relocation (due to sparse trees), so naturally the mechanic is the most useful class. However, this shouldn't be a huge problem, as dinosaurs will be slow to chase, due to the fact that every living creature is slowed - survivors and dinosaurs alike, but vehicles are not. Survivors are able to place the 1x1 barricades for free, instead of for 1 lumber (which are replaced by packed snow walls). There should be far less insects, and a few more tanky creatures.
The mountain lands has an emphasis on defending your ground, and as such will have more larger, stronger dinosaurs (T-Rex, etc), and plenty of roaming dinosaurs. Buildings should gain extra armour and damage to compensate, increasing the value of engineers significantly.
The swamp lands has an emphasis on sprawling, open bases, which grow according to the demand for lumber. Survivors should not rely on static defences, but instead on mobile weapons. Poachers and biologists will be the most useful, as they can move to defend any area, and are able to make good use of an open base. There should be very few large creatures that would raze entire bases. Instead, packs of raptors and medium sized creatures should be the most common, along with plenty of fliers and insects.
The tropical lands is basically the neutral land. There is a small bonus to survivor movespeed and health regen, and there might even be a few mini "quests" or similar things to perform.
