Planet Packs that work together

[Jcklemme]

So far I have the OPM , and I have D.A.R.T.  What else could I add that would not break a current game?  I'd like to maximize the amount of high quality planets I have in system, and preferably stuff that works with Parallax and/or EVE.

Also looking for recommendations for Interstellar systems as well.

you can also use mpe (minor planets expansion), works well with opm. https://spacedock.info/mod/2383/Minor Planets Expansion

if you are looking for interstellar systems, try Event Horizon or Real Exoplanets

I went ahead and just installed every single one I could find that was compatible with the current KSP version and then removed the low quality ones.
