OK, my perspective on this is that a lot of it stems from the lack of dynamic tiles.
What I _really_ want to see is for forest tiles to automatically sprout new trees at random intervals. However, I also want to see forest tiles to gradually recede if there is not a tree or stump standing within a certain radius. With a more natural back and forth, we get
1) more trees, with planting being a good way to protect a woodland as a whole from rapid deforestation, not the basic way of creating any tree at all.
2) more grassland, which means more cows, more sheep, more food choices for all players, newbies included.
At the moment we just have acres and acres and acres of clearfelled forest tile. Much better would be for some of that to regrow at a steady rate from the treeline, while the far edges receded into fields.
