Quote - Thanks for all that input. The thing is that with 50 textures people are attracted to different designs so there is no guarantee that if I were to release a product with less textures that I would get more customers based on those specific designs.

 this is the same fallacy which makes most open source projects have bad interface design.  most people do not want more choice.  they want things to be simple and reliable.   they want have to think about fewer things, not more.  making them compare and evaluate 50 different things is like making them go through shopping all over again just to use your product.  remember the goal is to make a picture, not necessarily play with your product.

take Stonemason's stuff for example.  incredible, incredible work. if he used the same logic, he'd make 30 different types of textures and props and parameters so people could make the kind of city they wanted.  instead he just does his thing and everyone wants his style.

lots of designs grouped in one place like that generally makes a product look cheap, like a bargain bin of shirts at Target.  if you want your stuff to look like quality (i'm sure it actually is quality already)  a) trust your style to appeal to people and b) use lots of whitespace.  crowding is for cheap bulk stuff, lots of whitespace is for high quality items.  check out ads in magazines.  look at a Good Housekeeping or similar magazine, and then look at Bazaar or Vogue.  the simpler the product and its presentation, the more it costs and the more people are willing to pay.   almost always, the cheaper knock-offs show more complexity (where the other hides it) and feature more variety.

do a few things very, very well and present them in a striking manner.  this market is actually very like fashion in that merchants rather than customers tend to define style.
