Hi, I'm new to the game and got frustrated with some of the pointless missions, i.e. fly a craft over this place at x feet above sea level. I'm looking to play a more science/exploring mission type game, I use CKAN for installing mods. If anyone can suggest a list of mods for craft parts, gameplay, a diverse research tree and visuals I would really appreciate it. Thank you all in advance, Nathangun.
