For my Khemri table here is the list of terrains I'm thinking about.
3-4 unes counting-as hills

(plus texture

)
2-3 ruined temples counting-as forest or hard terrain:

Forest with columns plus ruined sphinx and ruined walls.
Hard terrain with low-level ruined walls.
1-2 quicksand zones counting-as lakes (impassable)

1 oasis en counting-as marsh

1 tent-village counting-as zone urban zone

Not so fluf, so I'm not sure about this one...
3-4 desert cliffs counting-as impassable terrain

Your idea?
