Hello, there are currently options to allow windows programs to run on chromebooks, I would suggest googling them as I can not provide you with links for these. That is just one route that you can take to still play this game.

I searched for approximately a minute and found an option that was completely free. It would allow you to run a .exe file through a chromebook. Once again, as it is not an Oasis supported program, I am not able to provide you with links or files, but perhaps some of your server members, or friends who happen to use chromebooks, might know of programs that allow you to do this.
