Dunno if literally hilarious, but in Chrono Trigger you can act like a total jerk at the beginning of the game (eat some old dude's lunch; kick a lost cat out of the screen instead of taking it to the little girl who's looking for it; try to steal and resell Marle's pendant, etc.). Since you've just started this game you think there will be no consequences for all this but then two chapters later you're actually put on trial and it all comes back to bite you in the ass.
This right here is the mother of all subversive games. Even if some game had done something similar before, Chrono Trigger made it truly important.
