Links 2003 fan here. Nothing has come close to the options that were available on that game.Multiplayer was fantastic, you just met on a site and exchanged ip and played ladder matches, tourneys ,etc. Adding your own sound wavs was also cool.I have recently purchased JNPG and I don't think it comes close to TGC.
However the multiplayer component/community needs to be improved. A course I still remember fondly from Links 2003 was called El Scorpion,anyone else remember that one?
