Thanks for the feedback @SE_JonF, @jwatte.
We’ll have some flat-ish areas in the third landscape.
The reason we didn’t like to have flat areas in AL1 was mainly that the landscape size wasn’t big enough to have a believable amount of both flat areas and the surrounding mountains etc. so we could just let you use the flatten tool in engine and flatten the land where you want. With AL2 the landscape size are 4 times bigger and there’s plenty of room to flatten chunks of it.
