My first computer was a Compukit UK101 which had 16 lines of 48 characters where each character was an 8x8 grid of pixels. It had up to 8K of RAM (thats kilobytes, not megabytes or gigabytes!) plus 1K of graphics RAM.
I wrote a procedurally generated, open world, RTS (real time strategy) game with destructable environments which can now be played on any computer with Java installed, thanks to Tim Burton's UK101 emulator.
