Native

A game whose widescreen method is "Native" is a game where enabling widescreen can be done entirely from the in-game options menus. A game can only be considered "Native" if there is no way to improve the widescreen support externally. For example, if a game supports widescreen resolutions natively, but is vert- this way, and it is possible to make it hor+ via editing the .ini file, it cannot be considered Native.

Batman: Arkham Origins

Retrobooster

The cave shooter mechanics of yore, coupled with today's graphics. As the fearless pilot of a thruster-powered space ship, you must destroy aliens and rescue civilians whilst avoiding to bump too harshly into the scenery.
If Retrobooster's 3D models are arguably not the most detailed, the subtle physics and the special FX are indeed... really slick. Impeccable flightstick support and a DRM-free demo always impress, too.

This world was not made for you to understand.
