Myst vs S.T.A.L.K.E.R.: Clear Sky
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.
S.T.A.L.K.E.R.: Clear Sky
S.T.A.L.K.E.R.: Clear Sky is the second installment in the S.T.A.L.K.E.R. series and yet is the prequel to the original game. In this game, a group of stalkers have unwittingly triggered an explosion of anomalies when they ventured into the heart of the exclusion zone - the Chernobyl Nuclear Power Plant itself, turning the entire zone into an unstable mess that continues to quake with anomaly outbursts. Stalker factions have also erupted, further adding to the overall chaos of the region.S.T.A.L.K.E.R.: Clear Sky is essentially similar to the previous game, though it does have some significant improvements. For instance, the game is a lot more stable, which is ironic considering that all the storyline in this game talks about is how unstable the zone is. The weapons and armor in the game work better than in the original since they can, finally, be repaired. Artifacts are harder to find here but is a lot more rewarding and well, generally the overall setting feel a lot more realistic.
This is definitely a nicer game to play than its first game, but it's not really comparable to the third game of course. However, if you love the S.T.A.L.K.E.R., you might still want to consider buying all three games via its Steam bundle.
