Well first let's list what is special about private servers:
- Custom items
- Free premium items
- Custom maps
- Close community
- Active GM's
Now if we continue to brainstorm over each separate point:
Custom items
We've got the hotshot, the training weapons.
Free premium items
Have we got any custom sets?
Custom maps
Same as above.
Close community
Maybe some screenshots, with the right camera pans, of the forums?
Active GM's
Some footage of our active GM's.
Rizu: Some footage of all the GM's together.
I'll add more when someone comes up with an idea, see this as a summary post.
