Sorry if this has been posted, but I came across a nifty little Easter egg tonight. If you check out the file "actions_builds_leaderheads_specialists_atlas" in the art\interface\buttons directory, you'll notice a very familiar face mixed in with the leaders. Also, in the art\leaderheads, there is a special folder named "Sid" with everything you would need.

Got me to thinking that it would be quite easy to add Sid to your choices for leaders.

edit:

There is another Sid file and several possible placeholders, to include Caesar Augustus, in the art\interface\leaderheads folder, in case anyone missed it.

I think he is used the tutorial, but I havent played it.

yeah, he's your tutorial guide

yeah I saw him in the turtorial, ant thought "hrm, could he be used for a leaderhead".

Another update...I added a small mod in the completed modpacks section that replaces America with Firaxis and adds in Sid in the place of FDR. I didn't alter anything but graphic tags and names, so feel free to change everything else (like traits) as you see fit.

I also saw in another thread that barbarians can be modded as a palyable civ with Sid as their leader.
