[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

[PC98] Venus - ヴィーナス (1994)

How:
Read about the game from the True Love review on Hardcoregaming101.
Ending:
I finished the game with 3 out of 4 girls without walkthrough in one go.
Pros:
- Very nice character pixel graphics, fitting very well with the backgrounds
- Generally fitting music
- Many endings (each ending is an AV recorded by the main character for his almost bankrupt company)
Cons:
- Gameplay is very simplistic, just set a date and go there
- Very few places to visit
- Very few events
- House items have descriptions but no use at all

[PC] Beautiful Escape: Dungeoneer (2010)

Pros:
- Nice mood
Cons:
- Feels ripped (dialogues, graphics), pretentious (dialogues, music), finished quickly
- The torture mechanics sound interesting but end up being plain annoying
