[PC] Sanitarium (1998)

How:
Played the demo when it came out, finally bought it during Halloween sales at GOG.com.
Pros:
- Cool isometric view
- Nice music fitting well the creepy mood
- Plenty of cut-scenes
- Engaging story with a slowly unraveling mystery
Cons:
- Some game-breaking bugs and crashes
- Puzzles tend to be sparse and easy, they mostly serve to move the story along
- Lack of dialogue continuity; the character reacts to dialogue in a fixed manner even if he already has the information he needs

[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
