Great post,
Villagkouras
I know all of these games, but the only one I ever played (and completed) was Impossible Mission 2. I played the Amstrad CPC version though, which was 'lacking' a few parts of the game and could be gamed so that it always gave the same level layout - which resulted in the 'impossible mission' becoming a merely 'improbable mission'.
But I feel like talking about some old games, and these two came to mind.
Xenomorph (1990)
Dungeon Master had come and...mostly stuck around as the Best Thing Ever for Atari ST users, so naturally everyone and their grandmothers tried to cash in on it. One interesting effort was this game, a game where a transport ship suffers a huge malfunction and is forced to land on a research post that seems abandoned for 'some reason' (as if the game's title wasn't a tip-off).
Half the manual is just background story that explains how come you, the lowest-ranking member of the crew (with the possible exception of the ship's cat, Hydrant, which didn't survive the trip
) is stuck with needing to make the ship space-worthy again by switching out all the burnt-out chips on the circuit boards, as well as finding replacement fuel rods to fuel the ship. It doesn't take long to realize that you're the only living human on-site, and something has gone terribly wrong after a series of gene-experiments involving local samples. I don't think that the PC version is the best version to play, but it sure does convey an interesting atmosphere and pays tremendous attention to detail. It's a survival horror game that's tangled in the wrong game genre.
Murder! (1990)
Unless you read gaming magazines around 1990 (or actually had a copy of the game in your hands) odds are good you've never heard of this one. This is a 'private eye simulator' where you just happen to be present at a fancy party when someone gets murdered, and you're given 2 hours before Scotland Yard arrives and takes over the investigation. That everything is portrayed in black-and-white is deliberate, as the game takes place between the years of 1919-1945, the years that Agatha Christie was at her finest.
The gameplay involves finding clues, interrogating suspects, trying to piece together the events leading up to the murder and proving which murder weapon was used. The thing is, thanks to clever coding and the usage of 'seeds' the game has a couple of million cases to solve, so step carefully into the shoes of 'the Bloody Belgian Busybody' if you fancy a go at this game.
