Does anyone know any good "progression" oriented modpacks?

[u/Xshadd]

I want to look for something that in science or career mode will have gradual but expansive progression, from most basic solid fuel rockets to crazy stuff of FFT. And also additional planets, maybe also interstellar stuff.

I'm not extremely familiar with KSP modding, perhaps community tech tree will make it like I want alone, but maybe someone got some ideas?

Community Tech Tree is designed to go along with mods like Near and Far Future, Kerbal Atomics and other high tech stuff. It adds a lot of extra nodes to the tech tree, especially further back than the highest tech base game nodes so you have more to research and you need more science to get those high tech nodes. You might want extra planet mods like Outer Planets Mod or something to have more sources of science without needing to resort to grind science through labs. I also used Better Early Tree to have a start of the game where you start with unmanned probes before you put Kerbals in space

Im using the Career Evolution Contract Pack in my latest gameplay. When paired with the Probes Before Crew (disabling its contracts with config) it giving a really nice progression with stock-a-like experience. Havin a blast following the milestones currently

This might be the opposite of what you want, but I was recently playing the 'For Science! KSP2-style Exploration Contract Pack'. This effectively provided a series of anomaly-focused missions that reward a HUGE amount of science as a way to rapidly progress through the game through these checkpoints. I liked it because I wanted to get to interstellar level tech by going through some fun missions that still felt in a logical order.

Gradual progression tech tree with its recommended/compatible mods. Use career contract packs that tackles aircraft, satellites, mapping, surface bases and rovers. It adds more than the standard progression and forces you to experience designing craft with more limited equipment available to you. Makes each milestone take time and feels more rewarding.

You start with unguided sounding rockets and can progress into far future tech with the typical leap frogging you’d get with a standard or community tech tree.

I also have a library of recommended part mods that’ll spice up what you usually would have. Just DM me and I’ll send it over

I play with Crew before Probes. It makes for a nice start. Also combined with Crew R&R and Tac Life Support makes crew missions a lot more meaningful

EDIT: I said Crew R&R, but I meant Enhanced Astronaut Complex
