Rust vs S.T.A.L.K.E.R.: Clear Sky
Rust
Rust is hardcore survival game where the only aim for every player in the game is to survive. Being a survival game, your character will have needs that you'll need to fulfill or risk getting ill or worse... dying from it. There are tons of recipes for you to craft a wide variety of items from as long as you've got the resources you need, and you can also hunt and built a shelter.As fun as this game may sound, the community in this game can be a bit toxic. Most players have a kill-on-sight policy (even if you're naked and literally have nothing with you) and this means playing alone can be very frustrating. If you're planning to play this game, you might want to get a larger group of friends - maybe somewhere around 5 or more players - or you'll quickly realize you want your money back now.
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.
