I’m seeing reports in the forums that the GOG version of the game still has its LAN multiplayer. I only played a bit of Crysis multiplayer, but I can see why it would have been great. I was mostly on college networks at the time, so online multiplayer was rough for me unless it was peer to peer with someone else at my school, and hardly anyone had a computer that could run the game at the time; mine only got it running on low/medium settings.
