Theres an amazing WIP mod called Rails of War, I recently added it to my pack along with several other mods not you dont often hear about. You should check it out.
Another mod I added, ICBM has a regeneration explosive that regenerates chunks that you might have already blown up using an antimatter explosive...regenerates water, ores, everything goes right back to the way it was when you spawned, probably erases anything you changed. Could be useful depending on how expensive it is to build. Im thinking, quarry plus a twilight forest hollow hill, detonate a regeneration bomb.
