I figure even if nobody is replying with specific individual requests, you can kind of tell what developers here want to have available by what game devs are releasing.
I see a TON of horror games for example so horror themed assets are something I am prioritizing work on now. There are both 3d and 2d games and you can drill down with tags to try to get a sense of the proportion of various types of styles, etc. And then build to cater to what people find useful.
I am about to release an update to my little freebie blood fx pack for instance as that is proving popular and I will soon have both a free and a larger paid horror pack added, plus updates in various other areas. Lots of new texture maps, 3d assets, etc. Some of those are more general purpose nature, indoor items.
My asset pack shop is doing okay, has made a few hundred $ in sales to date, has 129 folllowers and 17 five star reviews but it's been many, many hours of creative work getting there and much more is still there to do.
