I've been a KSP player for quite a while now, and have used a large amount of mods since I first started. There's been a lot of amazing tech trees released so far - CTT, Kiwi Tech Tree, Tetrix, and more, but for whatever reason none of them "clicked" for me. Part of this was due to the fact the Bluedog Design Bureau, one of my favorite mods, wasn't supported by most, and the rest was just due to differences in how I felt part unlocks should be balanced. For a while I just would fix this by writing custom patches for the already existing trees, but eventually, this past September, I decided it would be easier to just solve my concerns once and for all by creating my very own tree. Now, four months later, here we are! The Skyhawk Science System has been careful curated to support most of the current popular mods in a way which allows for a realistic, but still fun progression from sounding rockets to interstellar starships, and also, adds in a few mechanics to both increase realism and provide some interesting choices for players.
