[PC] King's Quest VI: Heir Today, Gone Tomorrow (1992)

How:
Often heard of it as one of the best adventure games ever, got on Gog.com with the King's Quest 4+5+6 pack.
Points:
I managed to finish the game with 228/231 points without using a walkthrough (I actually needed a walkthrough just to open the ink bottle...). The only puzzle I missed was feigning death in front of the black cloaked man, since I got the correct lamp by trial & error. Still got the best ending possible.
Pros:
- Some memorable and diversified music
- Generally good voiceovers
- You get to ride a black winged horse to the realm of the dead!
- Direct references to previous episodes of the series
- Rather lengthy, with a great amount of optional content
- The second half of the game is amazing (realm of the dead + castle)
- Very nice and logical puzzles
- Great graphics and cool cutscenes
- The possibility to die or get dead ends makes gameplay more exciting
Cons:
- Some super-fast animation glitches
- Some audio glitches (sometimes the music volume covers the narrator's voice)
- Using an item or using an item on the main character give different results only with some items (e.g. the ink bottle must be used directly on Alexander to open it)
- The Isle of Wonder seems more like the deus-ex-machina of missing inventory items
- Once again a final love ballad
- Some tedious backtracking required
- Trial & error required to solve certain puzzles
- Dead ends (usually quite clear though)

[PC] Hamlet (2010)

How:
Read about it on Adventuregamers.com, got with the Bundle in a Box (Capsule Computers indie bundle).
Pros:
- Nice, colorful graphics
- Boss fights
- Some clever puzzles
- Fun setting and story
Cons:
- Extremely short
- Sold as a "classic adventure game"
- A couple of puzzles require quick reflexes

[PC] Hector: Badge of Carnage - Episodes 1-3 (2011)

How:
Heard about it on Adventuregamers as a iOS exclusive, then got it with the Humble Weekly Sale: Telltale Games.
Pros:
- Nice puzzles
- Very good voiceovers
- Smooth animations and graphics integrating well characters and background
- Cool cut-scenes
- Some amusing characters and situations
- Lots of humor
- Nice music fitting well the different areas and situations
- Surprisingly lengthy
- Overall fun, colorful and well balanced
Cons:
- Perhaps exceedingly rude at times (e.g. fill used condom with pee)
- Some glitches
- Some annoying characters (the DJ in the last episode, the kids in the park)

[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] Beneath a Steel Sky (1994)

How:
Played the Amiga demo as a kid, finally got it for free on GOG.
Pros:
- Excellent graphics and animations
- The Virtual Teathre engine retains all the good points from Lure of the Temptress and hugely improves upon them
- Voiceovers are so good and enriching that this is probably the first time I leave them on when given the option
- Amazing, compelling story with a great pace
- Very good and moderately challenging puzzles with some well placed red herrings
- Memorable characters and lines
- Some very humorous parts (e.g. the trial)
Cons:
- People tend to get in the way (especially Joey)
- Music quality could be better
- Some bugs and crashes

[PC] Teenagent (1995)

How:
Got for free automatically in my GOG account when signing up.
Pros:
- Nice and moderately challenging puzzles
- Some good red herrings
- Very nice animations and pleasant graphics
- Very good sense of humor
- Fun setting and immediate gameplay
Cons:
- A couple of illogical puzzles (e.g. using a pinecone to create a dart, using a ribbon to straighten up fork prongs)
- The inventory tends to clutter up

[PC] Dragonsphere (1994)

How:
Promoted on Gog.com as a freeware game, got it without knowing anything about it. Played it after reading hg101 review.
Additional comment:
Not quite as short as most reviews mention (I think I needed around 10-11 hours from start to finish). The slow movements might have contributed.
Pros:
- Very good graphics and excellent in-game animations
- Very good (sometimes creepy) music
- The game has a very immersing, serious atmosphere differentiating it from most other adventures in similar fantasy settings
- Great dialogues and overall very likable characters
- A very deep and intriguing story with cool ideas thrown everywhere and a dramatic turn of events
- There are some rather challenging (but fair) puzzles
- Some puzzles can be solved in multiple ways
- Death is automatically undone, with no need to reload
- Lots of interactive elements, with long text descriptions
Cons:
- Movements are rather slow and unskippable (e.g. when climbing the mountain)
- Mediocre voice acting, thankfully it can be turned off
- Perhaps too many red herrings (both useless inventory items and misleading puzzle solutions, e.g. the poems)
- The story can be "broken" in a couple of ways (e.g. by going to the Spirit Plane without knowing about the Soul Egg)
- The interface can be confusing as some objects have item-specific default actions, e.g. a hidden button on the wall has "Activate" as default action, and "directions" can also be examined (this is especially important towards the end of the game when a door must be examined to reveal the symbol of a crown)
