Player Punch: Floyd's "death" scene reportedly brought many players to tears.
Tearjerker: Mention "The Ballad of the Starcrossed Miner" to anyone who's played the game.
Stationfall
Player Punch: Floyd dies again, this time for real. And you have to shoot him.
Sequel Difficulty Spike: A rather extreme one at that. Planetfall was one of Infocom's easier games, but Stationfall is closer to expert level. A much larger map, the time limit is considerably tighter, and the station becomes deadly as the game progresses.
