There's a fair bit of misinformation flying around here. There's also some fact.
We'd like to hold a modding summit here at The Creative Assembly at the end of July. Maybe we'll hire a venue somewhere. The main thing is we can have these conversations with you ourselves, explain why limitations are in place if they exist, and help if there's any way we can.
If you're a modder yourself and would like to attend, drop me a line at RallyPoint@Creative-Assembly.com - else please pass this onto someone you know who likes to mod our games.
