Hi,
Their stuff looks top notch, I think they caught up and went past
Recast a while ago. They have taken some hints from Recast and they
publicly admit that (I in turn owe a lot to David Miles and his great
GDC presentation), and they seem otherwise like nice folks too :) They
offer steady development and paid support, something I cannot
guarantee for a project I do on my spare time.
