I'm just enjoying the expanded tech tree right now(interstellar,future tech,MKS). I found in standard career I burned through the tech tree so fast and made it to Jool too easily and quickly and found I was always wanting to go further(eloo is meh). So I'm pumped to have the challenge to try to get to another star system. Except I normally find career a breeze So I put it on hard mode added in life support mods and now I don't have my minmus to science farm early on lol. Anyways I'm enjoying my slow crawl to achieving light speed to get to one of these awesome new stars. Or maybe I will build some kind of long term ark ship with the deep freeze mod who knows!!
