It includes pre-made legions and praetors along with their art, but he shows how to add your own legions/praetors as well. It works with artefacts and relics too, but you won't be able to devise new mechanics, as such, but rather use existing ones. Choosing art... will be slightly harder. Hopefully, we'll build up a library of art for the mod and the community will be able to start modding SI!

It's still in testing stage, so any help would be appreciated, and even if you don't have time to help, take the time to have a look at it and see what you think!

v. 1.06 is now current.

Hey guys, just a quick shout-out to ring in the new organisational powers we've been granted. We've been made aware of people using pirated copies of SI attempting to play games. We wholeheartedly condemn this exploitation of all Vic's hard work and commitment to making and maintaining a fantastic game. As a result we request that any and all games started via RPSatan use the latest version of SI, available at http://www.crypticcomet.com/blog/ which at the time of posting is 1.05c.


We would like to thank everyone for helping to maintain the integrity of this great game and our community!
