Yes please! Achievements are a feature I would greatly enjoy in KSP. I could picture an addition, that lists your accomplishments inside KSP, as medals, trophies, ribbons or alike. Id think of that as an enhancement of the experience rather than a limitation. And of course a little checkbox in the options dialog to disable it for everyone concerned about immersion. To round it off those (KSP) Achievements could trigger the corresponding achievements for Steam-users as myself, nobody is left out. Its just a feature request, undoubtedly there are many more request equally or more important still requiring a lot of manpower, but for me it would mean a major improvement to an already awesome game. I've already had a considerable amount of fun hunting for meaningless, ridiculous and crazy achievements, some alone, mostly with friends, inside and outside the Steam platform. And I promise to rethink my life, if this feature is implemented. But until then, THUMBS UP for achievements! The game just calls for it.
