[PC] Call of Cthulhu: Shadow of the Comet (1993)

How:
Read about it on Hardcoregaming101, bought it on GOG during a winter sale.
Pros: 
- Cool creepy atmosphere and story
- Some nice puzzles
- Very nice graphics
Cons
- Spooky but very repetitive music
- Unintuitive interface, sometimes you must Use items, sometimes you just need to have them in your hands in the right place at the right time
- Easy to lose bearings in town, and understand which locations are accessible
- Slow dialogues
- Possible dead-ends
- Too much trial-and-error towards the end

The game comes with a separate mini-game called "Lovecraft Museum".

[PC] Sanitarium (1998)

How:
Played the demo when it came out, finally bought it during Halloween sales at GOG.com.
Pros:
- Cool isometric view
- Nice music fitting well the creepy mood
- Plenty of cut-scenes
- Engaging story with a slowly unraveling mystery
Cons:
- Some game-breaking bugs and crashes
- Puzzles tend to be sparse and easy, they mostly serve to move the story along
- Lack of dialogue continuity; the character reacts to dialogue in a fixed manner even if he already has the information he needs

[Amiga] Indiana Jones and the Last Crusade (1989)

How:
Played on the Amiga as a kid, never finished it because the game crashed in the catacombs. Eventually found it again in my Gamebase Amiga collection.
Endgame:
Actually I didn't manage to complete the game since I couldn't identify the correct grail to pick at the end (tried all of them --should have read a certain message in the catacombs in order to be able to finish the game). Obviously didn't feel like going through the maze sequences again to properly finish the game.
Pros:
- The game introduces the Talk verb and dialogue trees for the first time
- Very good graphics (only 16 colors!)
- Smooth animations
- Very good puzzles
- Cool, adventurous settings
Cons:
- Character interaction feels a bit rushed (especially between Indy and Elsa Schneider)
- The game follows the movie a bit too closely
- Terribly annoying maze sequences, especially in the zeppelin
- Very frustrating and repetitive dialogue puzzles, the only way to solve them is via trial-and-error
- Mediocre music
- Fights are annoying, useless and basically unwinnable
- The game starts very well, but completely changes for the worst after the catacombs
- I've never used the Load game feature so much in any other game before
- Dead-ends

[PC] Space Funeral (2010)

Pros:
- Very nice retro/punk/kitaroesque mood
- Incredibly fitting music
- Very funny dialogues and story (the Dracula part is especially amusing)
- A smart parody of the genre
Cons:
- Too easy, requires very minimal grinding so that one can safely ignore skills, items and weapons to finish the game
- Difficult to understand the map and possible directions of movement
