One of my favourite games of all time is the hallucinogenic 1970s weirdness known as Titan. Now reborn as a Java program Colossus.
Colossus is a Java clone of Avalon Hill's Titan(tm) boardgame. Right now it allows hotseat play, play versus a working but not very strong AI, and (new) TCP/IP network play. We're mostly working on improving network play and variants right now. Improving the AI will follow.
