Clamp-o-Tron's Core Modpack

for Kerbal Space Program, from ClampOTron

This is a pack designed to provide a fresh, challenging career mode play experience to people who aren't afraid of a little grind, complexity, failiure, or installing and maintaining hundreds of mods. It draws on stockalike parts packs like Tantares and BDB to give more options to the player, while simultaneously making the game much harder with stuff like JNSQ, Kerbalism, and Engine Ignitor.

System Requirements:
I run this quite well (usually yellow or green clock in flight) with 24 Gb RAM and i5-9400 2.9 GHz. The loading times are awful though because I don't have a good SSD :).
Higher than this could probably run it quite smoothly. If you've got lower than this, uninstalling some of the pretties might help.

Ideal progression:
This modpack is designed to give a smooth progression from aviation to sounding rockets to probes to crew to reusable rockets to alternative means of propulsion to colonies. Personally my favorite time in a career game is when the the largest dependable rocket is a Titan III or something, so it'll dwell there for a while. If you want to change stuff, just uninstall/install mods at will.
