We started a world using the SevTech: Ages modpack so that we can have a bit of a challenge. The last time we finished a long-term expert pack which truly challenged us was Project Ozone 2: Reloaded in Kappa Mode. Age of Engineering was peanuts! Hopefully this will be a good ride.
The starting was a little rough since I had no idea how to get things done in this pack. Luckily, the Advancements system was excellent at teaching me how to play the game in a new way. I was particularly annoyed by the unavailability of crafting tables and non-tedious chests.
Age 0 was a short journey but it reminded us of how fun it is to start a new world.
