Hey there, I guess I'm late on this thread (I've even missed the original, i think). I've discovered KSP in version 0.8.5. No mun, no map, no time warp, no persistence, no ASAS, no RCS, no atmospheric indicator, no struts, no nothing. Just one LFE (don't remember if the T45 was there, there was no gimballing), one LFT, one SFB, one command pod, two decouplers (radial and stack), some winglets... not sure if there was anything else... oh, one parachute, of course. Oh, and Kerbin's atmosphere was only 30km high, and ended abruptly: at 29km you were inside a very dense atmosphere, and at something between 29.5 and 30 km, you were at complete vacuum. It was kind of bizarre... I used an android app (KSP Orbit, it's still in the Google Play store) to calculate the orbital velocity necessary to keep a stable orbit, and also to calculate the DeltaV for orbital transfers (example: from 40km to 60 km). Without time warp, I had to use a timer to avoid missing Periapsis and Apoapsis. One simple mission would take easily 2-3 hours, just to achieve orbit and then to make one or two orbital transfers. And then calculate the DeltaV to reduce Periapsis to under 30 km so I could land safely. When the Orbital Map showed up, it was a real game changer. And then: the Mun! It was so awesome to just see it in the sky when it was implemented... I felt so happy when I finally managed to put a kerbal there in one piece (well, the ship fell apart, there was no such thing as "landing legs"). Those were the days... :-) []s mrfg
