Hybrids were planned to be added to this build, but there were too many things to fix and a series of real life events made that take longer. As a result, more hybrids will be added to 0.705. 5-6 rather than the 3-4 the recent poll declared.
Quick note on near future plans: 0.705 and 0.706 will be dedicated to adding hybrids and refining some variant designs.
The game was going so well, it's sad to see how dedicated he is to this hybrid system.
It creates so much work. Every new species will now require an increasing number hybrids with all the other races.
It's the same problem that lead him to rework the sizes, because of the ballooning number of animation sets.
I would have hoped for the hybrid system to inherit the attachments from one parent and have a small chance to switch some of the attachments for the ones from the other parent.
It would have required some code to determine which housing the hybrid ends up in and a change to the character system to disconnect attachments from the races.
But once those are done it would eliminate the need for additional hybrid races and open up a huge amount of possibillities on what combinations you can breed. The developer could then redirect his creativity to creating new races with unique attachments which would lead to a major increase of possible nephelym.
