How long you play KSP i mean the version

[Moon Goddess]

I read the title and thought you were asking how much time do I play each version, the answer to that is a typical process of "Oh new version, I'm gonna do it right this time"

Install,

Install updated mods

Play, install more mods as they get updated

play

install more mods

Game starts crashing from out of memory

stop playing KSP till next version comes out.

The real answer to the question you wanted is.

Right at the tail end of 0.17, but you might as well say 0.18 cuz it came out like 3 days later.

since 14.5 I remember buying the game for the sole reason that it had multiple ship saves and landing legs.

[SpaceSphereOfDeath]

played it since before minmus (what version was that?)

0.15 and 0.13.1 is when I started.
