[Source] XLGAMES, developer of ArcheAge, recently revealed a new game engine known as XLE (I reckoned it means XL Engine). According to the official description, “XLE is a open-source (MIT license) game engine currently in development.” Several screenshots of ArcheAge rendered by XLE can be seen at the source. ArcheAge is using CryEngine, and I guess XLE will be for future games.
