Hello WhiteMagicRaven,
an engine that supports different games ?
It must be Spike´s brother
But seriously, if your carefully read what DarkOne said, you will see that the engine, is only "capable" to load Daikatana maps. They are not playable and not even "walkable" due to clipping issues.
So the status is light years away from "supporting" Daikatana.
Just like Darkplaces can load Hexen2 maps now, but that was it. The complete game mechanic, HUD, inventory, ... is missing.
But nevertheless an interesting link (unfortunately 9 years ago).
Best wishes,
Seven
