What I find interesting is that the vast majority of users are in the US. I wuold have expected a 2-fold or even 5-fold increase over the next countries (in EU), but if I look for example at Germany, UK or France, there's a 10x to 50x discrepancy.
Seeing as those countries are usually very much into emulation of older systems, were flash games simply not that poular outside of the US?
Personally, for example, I had some flash games that I played, but it was definitely a niche at least among my friends/family at that time, even at school or university.
You are missing couple of points : awareness of such tool, downloading of huge archives, and strong collection interest in people. I know people who.str happy to play Mario look-alike.js game instead of figuring out retroarch.
Last point : flash games peaked when rest of the world didn't have very fast interest. Only 0.1% had it or interested in it
That explains why Africa and parts of Asia are not on the charts. But it definitely doesn't explain Europe. I don't know how much you know about Europe, but it certainly that third-world country you're making it out to be when Flash peaked....
