Hi

Im making a tactical fantasy rpg/management/survival game where you control a group of heroes set out on a journey. Lots of influences from Darkest dungeon and Battle brothers. Its good to have "civilized" enemy groups like goblins that can have different troop types, fortifications etc in each area.

My idea for 4 areas to traverse is this:

1. Temperate climate. Goblins and trolls and wolves to fight. Continue by travelling on with a caravan.
2. Still temperate but more dangerous. Maybe similar enemies I havent decided, maybe orcs (goblin-like but thougher)? Take a ship across the sea!
3. Desert. More undead, what else? Large lizards and scorpions? Maybe lizardmen (warhammer made them aztec-like but maybe they can be egyptian-like?) Take camel-caravan onwards.
4. Wastelands. Dry, hostile lands with lots of demons. The end-boss rules these lands, so corrupted humans (cult?) might work?

Any input? This is a bit similar to the diablo 2 setup (temperate -> desert -> jungle -> hell) but maybe that's not too bad?

In each area these are some dungeons scattered (like ruined temple, catacombs, caves, abandoned jail etc) so areas should not be too different to let me reuse some of these in several area settings...
