Started playing KSP at 0.7-0.8 (can't remember which), the days before struts, meaningful SAS, strap on liquid boosters (could only attach solids to the radial mounts), no symmetry or angle snap. Oh, and no time acceleration either. Every launch was an exercise in hilarious, wobbly, misaligned torture, with no ultimate objective other than highest escape velocity. My wife finally bought it for me for Xmas 2012, (around version 0.18 then) the lure of all them planets was too much for me to resist!
