I downloaded it, looked at it and played it briefly. More small hills with sticks, if I see correctly. I think it's great when the community gets something new :-)

So here are some suggestions from me:

It would be good if you rename flatlands_easy.scn.xml to vod.scn.xml or valley_of_death.scn.xml, the same for the thumbnail and the map.

Remove the capital letters from <group_id value="Valley_Of_Death"/> ---> <group_id value="valley_of_death"/>

Adjust the string in the language file: <string name="flatlands_group">Valley Of Death</string> --> <string name="valley_of_death">Valley Of Death</string>

If you rename the scenario file, rename the other strings too: <string name="scenario_flatlands_easy">Valley Of Death</string> --> <string name="scenario_valley_of_death">Valley Of Death</string> and so on.

That could kill savegames. But then your map will no longer be displayed as "Flatlands Easy" in the game. Or is this a tribute to my map? I would also be happy about a little mention ;-)

Because you took the light version of the map as base, you might want to adjust some animal values (almost no wolves) and the raider timers and values (10 years). Unless you want it that way.

It's become a nice terrain. Further much fun with tinkering.
