Portal: 3 Open Source Clones Compared
glPortal is a standalone game built on its own RadixEngine with its own included assets, so it doesn't require owning the original Portal. Portal 64: Still Alive is a demake of the actual Portal built for the Nintendo 64 and needs legally obtained original Portal game files supplied at build time.
