[PC] Gabriel Knight 2: The Beast Within (1995)

How:
Heard of it since Amiga times, got on GOG during a Halloween sale.
Pros:
- Relaxing gameplay, nice mysterious atmosphere
- Good acting with authentic German speakers
- Some nice puzzles
Cons:
- Many puzzles are just a matter of going back and forth talking to people
- Overly slow cutscenes
- Extremely tedious arcade sequences
- No subtitles
- Some aggravating pixel hunting
- Handwritten letters have keyboard-specific typos, completely ruins immersion

Ending scene, with my tiny 679/679 score in the top-right.

[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] Space Quest II: Vohaul's Revenge (1987)

How:
Got with the Activion Quests sale at GOG.com.
Puzzles:
As in all Sierra games I played until now, I never cheated by setting game speed to "low" in any occasion.
Pros:
- Genuinely fun to play, with some funny scenes (hopping on the keyboard when miniaturized!) and funny commentary from the game itself
- Amusing ways to die
- Some quite challenging puzzles and red herrings
Cons:
- The parser does not improve much upon the previous episode
- Some illogical puzzles (give the Cubix Rube to the beast?)
- Not much of a plot
- Less climatic ending than in the previous episode (just push a button, enter a pod and sleep)

An amusing Alien reference - if you get kissed, a baby alien will eventually come out of your stomach!

Final score, and Alien ending!

[PC] Space Quest: The Sarien Encounter (1986)

How:
Never played the game before, got during the Activision Quests sale at GOG.com.
Puzzles:
I only had to look up one puzzle, namely how to get the shard of glass from the crashed pod. I did have the idea of taking glass from there, but couldn't find any. It turns out that it only works if you examine the pod from behind (not from the side).
Pros:
- The command-line based interface is a favorite of mine
- Red herrings and moderately challenging puzzles make the game very satisfying to beat
- Amusing ways to die and optional puzzles (e.g. buying the wrong spaceship)
- The unfolding story remains fascinating, as simple as it is
- Likable main character
- Nice, tense escape moments
Cons:
- Some random, unpredictable deaths
- Parser is not so smart

Getting the maximum possible amount of buckazoids at the slot matchine.

My final score. Will I ever finish a Sierra game with the maximum score?
Basically I didn't talk to and kiss the Sarien guard this time around.

[Browser] Worldgate Ep.1-3 (2012-2013)

How:
Covered in the monthly freeware section on adventuregamers.com.
Pros:
- Immersive world
- Simple and neat graphics, music and sound effects
- Nice puzzles, some of them moderately challenging
- Intriguing twist at the end (chapter 2)
- Cool to meet the ancient beings (chapter 3)
- Cool wrap-up explanations of the puzzles and devices met in the previous episodes (chapter 3)
Cons:
- Some interface problems (e.g. to analyze an inventory item, you click on its bottom-right corner, which can also happen accidentally)
- Small continuity problems (the journal is updated in the middle pages if the player does thing in a different order)
- The inventory can grow out of the allowed space if the player has more items than expected

[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] King's Quest IV: The Perils of Rosella (SCI version) (1988)

How:
Bought the 4+5+6 bundle on GoG during sales after finishing King's Quest II.
Pros:
- Very nice graphics and fluid animations
- Nice, short music punctuates the main events
- Very logical puzzles, some of which are rather challenging
- Some lightweight creepy moments and night scenes
- The game changes to zoomed-in visuals in interiors
- Very likable main character
- You get to play as a frog!
Cons:
- It's sometimes hard to see where is the main character due to screen clutter (e.g. when appearing behind a tree), and it's easy to get stuck
- No sound effects
- Some extremely annoying arcade sequences (e.g. the usual narrow paths and climbing the whale's tongue)
- Some dead ends
- Unpredictable random events make puzzles more difficult than they should be (e.g. cupid taking a bath in the pool, the cave monster appearing at times)
- The parser is sometimes very strict (e.g. play sheet music), sometimes very forgiving
- Unnecessary items have just the standard description

[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
