What game (rpg?) is this

Decided to turn my comment into an answer.

The first picture you posted was a picture of Vector from Resident Evil: Operation Raccoon City. You can find a description and picture of him here. Additionally, if you search for "Resident Evil Vector" in Google images, you'll see a plethora of images of him.

The second picture is also from this game, although I'm having trouble verifying this with a reference or image. This is the best I could find (which also has Vector).

Edit:

Here's the info on Christine Yamata, the person in the second picture, also from Operation Raccoon City.

The character is from the box art (and other promotional material, such as wallpapers) of Heroes of Might and Magic V, altough the picture has been heavily photoshopped.
