One of the Best games to date. Great graphics, engine, physics, AI, and storytelling.
User Rating: 9.5 | Half-Life 2 PC
Well I have personally been trying out different engines and which is the best, like Unreal Engine 3 and Cryengine, but this game was made on a engine that cannot even try to be compared to the others. That is the Source Engine. The physics were remarkable, the graphics like lighting, animation, modeling, and water effects were outstandingly accurate. The Artificial Intelligence was very realistic, and the characters and story were original and unforgetable. This is one of the greatest games, as it set a lot of records, awards, and it is still the masterpeice of PC gaming. Acheivements are in this too, so there is a nice blend of challenges mixed in with the open world, sci-fi, horror, thriller, and humourous gameplay. Buy this, or try the Demo on Steam, its the best game you can get on PC.
