ideal for mining of course or mountain/tall builds
I also think that it would be great for farmers to have better tractors or even a combine harvester in the more modern eras. When thinking about lower tier vehicles, I would also think about adding restrictions and limitations based on professions? E.g. You have to be a miner to use a lower tier excavator (or it consumes a lot less calories), so miners don't become obsolete or people cut out the middle man because they can now use an excavator.
Dump Truck, fork lift, ATV, Motorcycles, and Speed boat. If space ever becomes a thing...spaceships.
Sunlight That just gave me a thought, what about in late late game, space exploration tech that lets you build out in space.
It would be good if in the future you made a suggestion per singular feature you want to be added, otherwise the overview over suggestions can quickly become difficult and voting on singular parts is no longer possible. In this case there already was a suggestion for kind of a steam excavator and another one for multiple other steam vehicles (but also an engine, that doesn't fit into the theme of the suggestion and also not into yours, so that part of the suggestion is now "lost"), which I have now merged into this as its also partly part of your suggestion. Not necessarily all voters on the steam exacavator may agree with the other vehicles you suggest though, so voting is now a bit off. At the same time it is important that we do not have any duplicates to vote on, otherwise it will be very hard to handle this tracker. So it is generally advisable to stick to one feature per suggestion or at least keep all suggested things to be of one tight topic.
Excavator?
