I agree... it's sad to see some old good products being retired and going away forever.

Eventually I will release as freebies here on Renderosity some products I created years ago.
I used to sell them in my site, now they look slightly dated, especially materials and textures, and today probably I would create more realistic and detailed meshes (10-12 years ago was not recommended to use too many polygons) but someone could still use and enjoy them.
Sharing them with people is a better option than abandoning them "forgotten and dusty" in my Runtime.
