So I did some rough planning, and theres about 14 different 'areas', some of which are similar environments:
Kingdoms (blue):
1. Green area below mountains at far left (forest)
2. Center of light green area in middle of large continent (plains)
3. Peninsula around lake at top part of large continent (forest/lake/port)
4. Light green area at top of bottom continent (island/tropical)
Fields (yellow and red):
1. Mountain area below desert at left (mountains and mines)
2. Desert area at left (desert)
3. Mountain area above desert (caves)
4. Plains area around center (plains)
5. Forest area at top center (woods)
6. Marsh area at bottom center of big continent (marsh)
7. Forest area at right of big continent (forest)
8. Snowy area at top right (snow forest, snow mountain)
9. Volcanic area at middle of bottom continent (volcanic)
10. Forest area at bottom of bottom continent (woods)
Seem good?
