[PC] DoomRL 0.9.9.7 (2013)

How:
Don't remember, probably found after playing NetHack.
Pros:
- Very accessible for roguelike newbies, the complexity can be explored gradually
- Very replayable, provides several challenges and achievements
- Great atmosphere
- Winning is not close to impossible, unlike many other roguelikes
- Allows for quick sessions
Cons:
- Music is too much intense and distracting

One of my winning characters in the Angel of Berserk (melee-only) challenge.

My PC as of April 2018. Won a total of 3 games (2 easy, 1 medium).

[C64] Halls of Death (1983)

How:
Searched for other C64 rpg's on CRPGAddict master game list after enjoying Sword of Fargoal.
How to play:
"/" : down
":" : left
";" : right
"@" : up
"+" : use stairs
"p": spells
Movement can be made faster with F1.
Spells: Sleep (1), Teleportation (2), Lightning (3), Fireball (4).
Levels:
I was proclaimed: Apprentice Bumpkin, Yokel, Trainee Warrior, Warrior, Swashbuckler, Seasoned Adventurer, Hero, Dragon Slayer, Champion, Necromancer, Sorcerer, Superhero, Guardian.
Pros:
- Cool first-person view animation on the lower right
- Spells can be used to destroy walls in the dungeon
- The game forces you to take careful choices, because:
   1) a successful game sees you going back to the surface (i.e. you need to backtrack or teleport)
   2) stats grow with items found in the dungeons, and decrease with enemy encounters, traps and magic spells
   3) game ends when any of the three stats (Strength, Psionics, Constitution) falls below zero
   4) using spells consumes both Strength and Psionics, is not always successful and becomes mandatory at the deeper levels (vs wraiths)
   5) Strength and Psionics points can be transferred to each other with a 1:3 ratio
- Gameplay can get addictive and very tense especially during the ascent phase
- Successful ascents are very rewarding
Cons:
- Fight success only depends on the strength and magic levels of the PC
- Grinding is possible only to a limited extent, as it depends on what items you find in the dungeons and the outcome of encounters
- There is no use for the collected treasure
- No sound
- The time you can spend in the dungeon is only dictated by luck, since Constitution depletes as you fight and it can only be recovered by finding Stamina, which is rare

This is as far as I got. Getting the Lord of Light rating is a matter of grinding for treasure, perhaps one day I'll do it.

[C64] The Sword of Fargoal (1982)

How:
Read about it on CRPGaddict, bought C64 Forever and played it right away.
Note:
Apparently this is the first game ever with random dungeons.
Pros:
- Simple, yet addictive quasi-roguelike gameplay
- Some interesting game mechanics (proximity sounds, pit traps usable as stairs) and magic spells (beacons, teleport)
Cons:
- Dungeons are quite repetitive
- The game gets almost unplayable from level 15 down
- Very few types of monsters
- Waiting at the temple to heal the character can take a lot of time

Actually, of those 8:54 hours several were spent regenerating health while doing something else.

[PC] King's Quest V: Absence Makes the Heart Go Yonder (1990)

How:
Bought the King's Quest 4+5+6 collection from GOG after playing King's Quest II.
Additional comment:
Not nearly as unbeatable as it is usually depicted.
Pros:
- Excellent graphics and animations
- Very nice music all throughout
- A cool adventure with lots of travel and a compelling story
- Nice, challenging puzzles
- Some puzzles are solvable in more than one way
- Connections with previous games of the series (e.g. Manannan cat) is rewarding for fans
- Fun and slick gameplay
- Nice graphical choice for the windowed interiors
Cons:
- Packed full of dead ends
- Cedric the owl has no use except at the very end
- Voice acting is generally mediocre
- The final part is very frustrating
- Must resort to save scumming in order to finish the game
- A couple of illogical puzzles (e.g. the moldy cheese to activate the machine)
- Some graphical and sound glitches
- The game annoyingly interrupts with a warning message every time a cutscene is going to start
- The desert maze is uncalled for

[PC] Diablo (1996)

How:
From the old days of double-blind game swapping with friends. Couldn't understand the gameplay at first, but a second re-evaluation got me nailed down to the chair for days.
Pros:
- Immersive world
- Cool isometric graphics
- Excellent music
- Very good replayability value due to the random generation of dungeons and side-quests. Playing with three different characters also provides rather different experiences
- Immediate and fun gameplay
Cons:
- It's too easy to max out characters and beat the game
- Gets repetitive after a while
- Role-playing elements are rather limited
