Thanks to recent advances in technology, it has been possible to port Progress Quest to run in your browser. You no longer need to download or install anything to play Progress Quest; just hit the button:
Does that sound easy to you? Well it wasn't; we started with hardware emulation of a 80386-equipped PC clone running a novel Windows XP compatible operating system called ProgrOS, implemented in a clean room in the Seychelles by a team of people who had never programmed before (to keep the lawyers at bay).
Unfortunately that wasn't fast enough (there was too much lag death),
so we instead emulated the much faster Cray-2 supercomputer and ran
the 80386 emulator in that. But the 80386 kept getting hot, so we
switched to a 6502 overclocked at 120GHz with emulated liquid helium
coolant, and ported ProgrOS to that.
