The spruce forest biome, especially when near a large lake, is my absolute favorite places to settle down and explore. But it would be nice if there could also be a "Redwood Forest" biome which redwood like those in California or giant sequoia. I imagine something of this size would take about 40 hits with a log and yield a similar number of logs
Also, as some have noticed, the spruce trees cannot be re-grown to the full height they are found naturally. i wish this would change.
Long term, I would hope procedural generated trees eventually replace models. Or perhaps someone can write a plugin to place such trees in the game. As lovely as the game is already, you can kinda tell that there are only 1 or 2 models of each tree type rotated at a random angle.
