Kinda blows that It's shipped as gigantic compressed zip file. I happen to have the space for it but not double so I can actually use it. Shipping 10GB standalone chunks or just totally uncompressed would have been so much easier. I'm pretty sure all torrent clients could handle a couple hundred thousand files just fine.
Note of caution to the hoarders: I had a copy of flashpoint 11 on one of my drives and recently tried to move it to another disk... after two days of robocopy doing it's thing less than half of the files had been moved.
Obviously 1.4TB is enormous so long copy operations should be expected, but the sheer number of files makes it hilariously difficult to manage if you ever want to move it after extraction.
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....
