XL Engine

The XL Engine is an engine that runs the “XL Games”, which are enhanced remakes/ports* of the classic games. Essentially they are remakes in the spirit of a port, or to put it another way, they emulate the original games and then provide optional enhanced features on top in order to improve playability and visuals. All these games will be able to use the “Pure Renderer”, which is a software renderer that can support the original 8 bit rendering and resolutions. Basically this means that you can play the games as they original looked and played or play in higher resolutions and color depths with a variety of enhancements. You choose how close to the original you want the games to be.Games that are currently supported, or that will be supported upon the next release are:
 
DaggerXL - Daggerfall (previously listed by itself here on ModDB)
DarkXL - Dark Forces
BloodXL - Blood
OutlawsXL - Outlaws

This is still a work in progress, not all games are fully playable yet. To follow along with the current progress visit the website and forums.

So why would you want to play these classic games using the XL Engine instead of the originals?
A variety of reasons:

• Modern OS support without worrying about tweaking for performance or DosBox limitations.
• Cross platform support coming in the next release.
• Potentially higher framerates and smoother gameplay.
• Optional modern control schemes such as mouselook.
• Increased moddability as the project matures.

• In-game console for modifying settings.
