You can read the guide here: GC2 & Dark Avatar Guide
It's very important for you to know the purpose of this guide.
1. It is not
to cover every aspect of the game. It's meant to cover some of the things that are easy to forget, confusing, or difficult.
2. I'm not a web designer.
3. I still have a few pages to add. Custom Races, and a compilation of how the game cam stay fresh and fun (i.e. no next turn syndrome, or super redundant gameplay)
4. I still have to optimize many of the pics. Some of them are pretty big, but after some 30 hours of working on this thing... I just wanted to get it out there.
5. Feel free to post items you'd like me to add, whether it's a single point or a whole page. I'm looking for things that people often overlook that makes the game easier to manage and/or more fun.
