As all we know Adobe is going to remove the flash support in 2020 and after that you will not be able to enjoy those online games through flash, to remind the old times what is your favorite flash game? mine is Happy Wheels and Line Rider
If flash is no longer a moving target and instead a horrible mess of spaghetti and the years of directionless creation surely the open source implementations can get it sorted for those that want some legacy stuff.
Anyway sure something can run as long as you have the hardware/emulation and software to run (no lacking server components or anything). However similar to how few are making qbasic games in the same way they did in the 90s and it could be said to be dead or primarily the domain of people enjoying messing around the same will likely be said of flash when this happens. If nobody has it on their devices/browsers then the incentives to make and maintain existing games will drop off a cliff (more so than it already has).
Though it also means that support will be progressively dropped from most and all standard browsers and OSes, old tools will stop working on new machines and/or imply a very big risk of vulnerabilities and attacks, and you will end up needing to go through some difficult process just to use/play things done on flash. It will not be out-of-the-box anymore.
Umm...I think you might have the wrong person, since that may as well have been written in Chinese. I have nothing to do with the management of this site, nor have I ever been involved. I'm just a member, and hardly even qualify as that...like I said my last post was almost a year ago lol
