I think you nailed it. If I stumbled across these I would never download them because I tend to notice something new and unique and these look exactly like more of the same. It makes sense that if you make something similar to 1,000 other games that being successful would be like getting a 999 on a thousand-sided die. Not to imply that it is easy to make something new (and good.) I have been working on a prototype of a game and the first feedback I got was all about how it was different than others games and that's bad. Trying to create something original is definitely swimming against the current.
