I came across this Flash game 'Alone in the Park', which I thought I'd share here, because it reminded me of SC2 in some ways, specifically in its humour, clever writing, exploration, and a "where are they now" sequence at the end. The humour however is different from SC2's, so it may not be for everyone, although I personally liked it. It is sarcastic and cynic, with the narrator mockingly commenting on your progress.
