I made a couple arcade minigames in tomenet. They're like Smash TV and the Tron light cycles game. Check em out at teh arcade server. Hit ? ingame for instructions.
Funky macros are required to play. My macro sets are downloadable from the downloads page here. The ingame help explains how to make your own. In my windows tron macros: f3 joins game, f4 starts, f5 lists options. Options can be changed by saying stuff like "moar speed" "less length" "walls off" etc. In my smash macros, f1 enters game, qweadzxc set firing direction, s is cease fire/bandage.
