Now it’s your chance to get involved in the game. You will find an explanation of the Silversword Script Language on the forums: http://silversword-rpg.com/phpbb3/viewtopic.php?f=2&t=760. Just try to create some lines of Script code, it’s not that hard. If you send me your scripts, I will try to integrate them into the upcoming extension of the game. Or maybe even into the core game with one of the next updates.
Although I have no graphical SDK for Silversword, you can nonetheless use the commands to make a decent quest line. I will help, test and correct you in this process of course. And if you really want to get into it, I can provide you the Silversword Map Editor (Mac OS only!), where you will have some nice features for editing maps.
Take the chance, be part of it! I am looking forward to your creativity.
