Okay, I know this argument is probably intractable and will go on ad-infintium. I have this to say: This game is open and flexible, play it how you want. That's the joy of a game like this that's s blank canvas. Some people use MechJeb, some don't. Some people like Mods, some don't. Some people prefer developing SSTOs, others prefer rockets. Some people mix and match everything. That's the beauty of a sim like this. It's your baby, do what you like. I really congratulate the Squad for making the game so open and flexible that so many different ways to succeed (and fail) exist. I think everyone agrees there. --- The part below this line is only my opinion and experience --- For those that want to use it, MechJeb 2.0 is massively impressive. It actually TAUGHT me orbital mechanics. If someone had asked me what a Hohmann Transfer was 2 weeks ago I'd have looked at you gone-out. Now I can explain exactly how they work. Saved me a lot of reading I, personally, am interested in building structures in space and on foreign worlds, and colonising the system. I am not a fly-boy. I don't want to break any altitude records on 2 quarts of Vodka, I want to develop reliable and proven systems I know I can use to get stuff *up there* and build my little empire in space. Along the way I'll develop cool stuff and work out how to get rid of all my space junk, build on orbit and resupply my stations and colonies. I don't want the routine junk to get in the way. BUT that's just me, I want to play like that, it doesn't mean it's right or wrong.
