[Amiga] Curse of Enchantia (1992)

How:
Heard about it since Amiga times.

Pros:
- Nice graphics and smooth animations
- Silly humor

Cons:
- No dialogues
- Very illogical puzzles
- Cumbersome gameplay with unclear actions, mostly trial and error
- Too many red herrings
- No item descriptions, sometimes it's difficult to understand the graphics

Trapped in a coffin. Actually, asking for help doesn't help.

[PC] Gabriel Knight: Sins of the Fathers (1993)

How:
Got on GOG during a Halloween sale.
Pros:
- Good puzzles, not too easy
- Very nice graphics and animations
- Cool, captivating story
- Very good voice-overs
Cons:
- Music is not very fitting most of the times

My final score. I forgot reading the newspaper once.

[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] King's Quest VII: The Princeless Bride (1994)

How:

Got it from GOG during an Activision Quests sale.

Pros:

- Great animations and backgrounds
- Some nice puzzles
- Some nice settings (e.g. Ooga Booga)

Cons:

- Excruciatingly slow gameplay and animations
- No subtitles, with lots of badly recorded / over-the-lines voice acting
- Uninspired music

The goblin enjoying the romantic moment is amusing.

[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] Alter Ego (2010)

Pros:
- Beautiful graphics
- Gloomy, dark mood
- Tension builds up nicely as theories are made and the mystery unravels
- Great voiceover
- Quite entertaining from start to end
Cons:
- A bit too much on the easy side
- Music should be more present throughout
- Some animation glitches
- The ending is totally unrewarding
- With a few touches this could have been one of the best horror adventures ever
