My download stats on ticalc.org for monochrome calculator games have dropped significantly after the TI-84+CSE came out. The trend seems similar for popular ASM games as well, which often gets overshadowed by color BASIC games now. It seems that 83+ stats are now on-par with what TI-83 and 86 games were getting a few years after the 83+ came out. In my case, I think my three color releases get half of my total weekly download stats.
I wish that the HP Prime was more popular, though, because its BASIC-like language is so powerful that screenshots of programs made in it could be mistaken for TI-Nspire ASM games:

But again, with languages this powerful, you lose the old-school factor of working around 15 MHz hardware limitations, so some people might not find it as entertaining. Plus, part of the reasons why HP PPL is so fast is that the calculator runs at 400 MHz with rumored hardware acceleration.
