While some owners of Metro: Last Light and Metro 2033 feel they should be entitled to a free upgrade to the spiffed up Metro Redux remake, 4A Games feels offering owners of the original games a 50% discount on the remade bundle is "more than fair," offering those who think otherwise the option of not buying Redux (thanks GameSpot). Here's a bit:

For sure, Metro 2033 Redux is a far more significant upgrade over the original than Metro: Last Light Redux (and we're not trying to pretend otherwise).

We think the 50% discount is more than fair for the amount of work that has gone into this title. It is a complete remake of the original game in the latest engine, that will offer a significantly different experience from the original throughout with improved graphics, performance and gameplay.

Metro: Last Light Redux, we will readily admit, does not represent as significant a change over the original. So why the same 50% discount and not more? Why not just patch the game?

The latter proved to be impossible for a technical reason. Because of the changes to the engine, which necessitated dropping 32-bit support; we literally could not 'patch' the game.

In fact, both Redux games will exist as new titles in your Steam libraries, and the originals will still be there.

So why ‘only’ a 50% discount, the same as 2033?

We felt that because the Redux version also included the DLC in addition to the new game mode and enhancements, that was also a fair price.
