Myst vs Thief
Myst
Myst is one of the world's most highly-acclaimed puzzle-adventure game that's set on an island where every object can provide you a clue to revealing an ancient mystery. Filled with challenging puzzles that will give your brain a good workout, the game has astounding graphics for a game from its time, offering players the sort of realism and immersion they have never felt before.A classic and a timeless game, Myst has inspired a generation of gamers and gaem developers and is still influencing the development of some modern games. However, the Steam version of this game tends to be a bit crash-happy, making the game a real pain to play. You might want to try other versions of the game, like the one from GOG, instead.
Thief
Thief is a stealth-based RPG where you assume the role of the Master Thief, Garrett. Although he has been relying on his skills to survive so far, the revolution that threatens to break the gates, unleashing a bitter and bloody conflict between the upper classes and the common folk, will upend his life and force him to finally choose a side. With Garrett's wide arsenal of skills and tools at your disposal, you'll need to covertly infiltrate mansions, sneak across rofftops, and take out unwitting guards quickly and silently. The AI in the game is rather clever as well and are very well-aware of their surroundings, giving the game a higher degree of difficulty than you might expect.Every aspect in the game caters to the art of stealth, be it sneaking along a wall or quietly wringing a poor guard's neck. So, if you enjoy stealth-based games, you'll definitely love Thief.
