User blog comment:Chaosian/Poll Results 19 - Why is it that you like Metro 2033?/@comment-1403643-20120129224328/@comment-1932315-20120130200642

I got the "aliens" because Roadside Picnic is indeed based on aliens in the same way that Metro 2033 is based on nukes, not that the game enplanes if it has any kind of different plot (though I haven't played through the whole of a single game).
