Pros
- A stand alone game/mod for STALKER so the base games aren't required
- All the maps from the 3 games are present jammed into one,
- You can play as other different factions as well. Monolith, Duty etc
-You can customize your own experience before you start or in the settings to have the gameplay you want


Cons
- Playing the Trilogy is somehow err.. required in order to get the grasp of how STALKER is played, Oh and since it uses the same maps you can get familiar right away
