Tomb Raider: Legend

Native widescreen support. Just be sure to choose "widescreen" in the "Display" options.

The game grants more visibility horizontally. True widescreen HOR+.

The game only supports 2 aspect ratios: 4:3 and 16:9. The game allows you to run the game with either aspect ratio in any resolution. You can run 16:9 aspect ratio at 4:3 resolutions and vice versa. The game does not support 16:10 ratio, but still looks good. People are a little bit skinnier in 16:10.

The hud does not stretch.

NOTE: If playing on a 16:10 monitor, it will, like the 3D world, be very slightly stretched vertically as it is rendering a 16:9 aspect ratio on a 16:10 monitor. This stretching is not too noticable. (Shown below)

Cutscenes are handled with the ingame 3D engine and are also HOR+

As cranky stated, the forced aspect ratio hurts the overall score in an otherwise perfect implementation of widescreen support

edit:
for correct 16:10 -> 1920x1200 use Racer_S Fov tool and set the values to
Aspect: 0,822
Fov: 1,082
But mind you, as you will encounter some misaligned sprites if you will use this FOV hack. This tool does not work with the Steam version.
