Perhaps related, but I would really love to have better descriptions from the area selection screen. I like the challenge that several of the areas bring (Deserts, Glaciers, areas lacking rivers), but as it is you need to find such areas by selecting a place with no trees/ no vegitation, and even then it isn't assured.
It doesn't make too much sense to be to be able to influence the land with points, though; I think that an area should be what it is when it is generated, really. I think it would make more sense to be able to pay points in order to gain better support from the surrounding civilizations. Some examples:
400 Points - Civil Engineering: Begin the game with a trade depo, wagon-worthy road, and an outdoors well.
300 Points - Local Hunters: Hunters from a nearby human town are allowed to hunt on your lands, thereby reducing the threat posed by vicious Elephants.
200 Points - Elven Contact: Elves will come to trade before the proper noble arrives.
100 Points - Bribe Goblin Civilization: Goblins leave you alone for a longer time.
50 Points - Bribe Kobold Civilization: Same as above, but cheaper because kobold pose less of a threat.
0 Points - Insult the King's Mother: Starting relations with your parent civilization are much worse than normal. Dwarven caravans visit infrequently, and nobles come in fewer numbers.
If something of this nature was added, I think that it would make sense to use the same point pool as is currently used.
