Myst vs Portal 2
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.
Portal 2
Portal 2 follows in the footsteps of the award-winning original while continuing the story of Chell and Glados. Now with both single player and a 2-player cooperative mode, Portal 2 ramped up its game with a plethora of new, challenging puzzles, a storyline that's a lot richer than before, and more advanced and realistic physics that will govern your gameplay. Interestingly, the game also includes editing tools, allowing players to create their own puzzles which can then be shared for all to enjoy.Portal 2 is definitely a much better game in the series and if you fancy giving this franchise a chance, you might want to jump straight to Portal 2.
