[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
- Some frustrating pixel hunting

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] I Have No Mouth, and I Must Scream (1995)

How:
Read about it on videogame magazines at the time, bought it on GOG during a winter sale.
Pros:
- Very cool graphics
- Six different settings with cool story, cool characters, great dialogues, and nice puzzles
- Amazing mood overall
- Different ways to do things
- Very good voice-overs
Cons:
- Some glitches and dead ends. I had to resort to a walkthrough to get the correct sequence of actions to finish Garrister's episode (even though I did the same things on my own, but in a different order).
- Some showstopping bugs
- The MIDI soundtrack is a bit neutral

Cool Alien-ish prehistoric mood

[PS3] Beyond: Two Souls (2013)

How:
Read about it on Adventuregamers.
Pros:
- Stunning graphics and settings (snow, underwater, guerrilla, etc.)
- Engrossing and captivating storyline
- Diversified gameplay throughout the story, mixing different genres
Cons:
- Limited interaction, mostly just a matter of following instructions
- Some annoying timed reaction moments with confusing mechanics
- No puzzles
- 90% sad / depressing mood

[PC] Harvester (1996)

How:
Got in on GOG during a winter sale.
Pros:
- Multiple ways to do things, and optional paths
- Captivating story, cool endings
- Nice in-game videos
- Some nice puzzles
Cons:
- While you can type questions in dialogue, each NPC only understand specific keywords (e.g. you can not ask your brother about "dad"). Then it is useless, just keep all the keywords in the list.
- Lots of game glitches
- Uninspired, repetitive music
- Tedious action sequences that just consist in button smashing
- Some annoying pixel hunting

Might as well be taken from a Lynch movie

[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] Ultima II: The Revenge of the Enchantress (2001 EGA upgrade) (1982)

How:
Got it with a Ultima I+II+III sale at GOG.
Pros:
- Exploring the world across time and space can be fun
- Better monster sprites in the dungeons
Cons:
- No diagonal movement (while monsters can)
- Progress is achieved by randomly talking to all characters and slaying innocents (e.g. prison guards) in order to access otherwise unreachable areas. This kills role playing completely.
- The game is basically a long, unrewarding, extremely tedious grinding fest.
- Everything must be obtained with money, which is obtained by grinding, or by random drops by killing thieves. I did not visit other planets because the fuel drop was too rare.
- Overworld monsters are too rare
- Still no music
- Planets are useless
- Too many ingame jokes

My final character.

That L-shaped piece of land is Italy. I am passing Gibraltar strait with my frigate.

I made a bridge with boats.
