[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.

[PC] Portal (2007)

How:
Knew about it since HL2, got on Steam with a daily sale.
Pros:
- Immersive and addictive gameplay
- Amazing atmosphere
- Surprising turn of events near the end
- Excellent voice work and amusing script
- Cool puzzle mechanics
Cons:
- Graphics are a bit monotonous
- Music is a bit lacking

[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] ~airwave~ - I Fought the Law, and the Law One (2011)

Pros:
