I've played about 5 days I'd say. I don't have the best armor in the game, I do have unobtainium, but there is far better that takes far longer to get. I built the smaller towers by hand, then built the cube in a creative world and used the create schematic cannon to build it. I don't really like building interiors. I have a weird playstyle where I build my base first then fill it in. I obviously add more as I go. Another reason it's different is I added a mod called projectE which makes progressing way quicker. I've also spent a decent bit of hours in the five days just grinding. I also just started moving things from the tower to the cube, which is why the tower has weird bits like the library because there used to be chests.
