Craftologia is a pack that focuses on making more realistic and challenging crafting recipes, which also improve the relationships between the different mods on this pack, giving many items more uses outside their own mods scope that otherwise would become useless once you complete them and move on to other ones.
The idea of this pack is giving the player a feeling of realism and progression with each crafting, ensuring at the same time a very long gameplay experience in order to explore the different mods and complete this pack. To help in this purpose, the pack provides a broad set of building and decoration mods, so the player can also use some of this time making nice bases and buildings.

FAQ

Can i make modifications to the modpack for personal use?
I have thoroughly related the mods via its crafting recipes, i also tested and adapted the config for the modpack as it is. So you may see unexpected behaviour, gameplay breaking or game crashes if you add new mods or remove any of the mods present in this modpack. You can however edit the config files to fit your needs if you know what you are doing.

Is this just a grindy "expert" modpack?

Recipes have been changed not for the sake of requiring more materials so it will take more time to progress through this modpack, the idea is that in order to create something complex you first need to acquire the know-how and ability to produce/obtain the simpler parts it consists of. A lot of time and effort has been invested in this part, giving you a more realistic feel every time you craft something, 45 custom items and blocks were added for this purpose. Futhermore, in some cases crafting recipes require you less materials than default.
The exception to this is Dimension Builder from RFTools, which is the hardest and the last recipe of this modpack for obvious reasons.

Can we play this modpack on a server?
I will be working on the server files soon.

Can you change this recipe/config?
Sure, i am open to changes and suggestions, feel free to discuss it here.
