Your Tech Expansion server, with the useful bits included.
Host your Tech Expansion server
Tech Expansion is available for Minecraft server hosting with CreeperHost.
A fan's attempt at remaking davqvist's Age of Engineering(AoE) in Minecraft 1.12.2.
Tech Expansion is similar to AoE, but with many "quality of life" mods added. Some mods were not ported from 1.10.2 to 1.12.2, so there are some significant changes to the progression(the biggest change is removing NeoTech & Extreme Reactors and adding NuclearCraft). More info is in the in-game guide.
Automation is the name of the game here. Many big tech mods are included as listed in the Relations tab of the modpack page. The quests show you the general progression for certain items that must be crafted to progress. Most times, the quest item is a crucial component to build all of a certain mod's machines. Ex: Machine chassis from EnderIO. Due to this, there are certain sub-quest items/machines that must be crafted. Other than these few, you are completely free to skip entire mods or spend a long time in one age before progressing! The latter is highly recommended at certain points so that you set up some infrastructure that will last for a while.
This is a pretty good guide from the original. Most tips are still valid.
Find a bug or unintended interaction? Post to the Issues tab! Still working out some of the kinks but nothing game-breaking has emerged yet.
Recommend no less than 4 GB RAM.
KNOWN BUGS:
Hopper recipe won't show that only the aluminum recipe works
Clipboard texture not correct when in inventory
Nuclearcraft electromagnets won't take a charge. This should be fixed if you delete and regenerate the Nuclearcraft config file
Got questions? 
Yes. CreeperHost modpack pages link into ordering with the selected pack ready to install. You can also change versions or pick another supported pack later from CreeperPanel.
CreeperPanel is built around real modded servers, including update paths that aim to preserve user configuration changes where supported instead of treating every update like a fresh install.
Eco can work for lighter packs, but Premium is the recommended CreeperHost range for modded Minecraft. Premium gives stronger hardware, Turbo Start, Bonus Memory, and Ask Theo where enabled.
