While I appreciate the link provided, is there going to be a PDF manual for 2.5 that is updated from 2.0? It's handy to have it on your desktop while playing, instead of having to go online.
Still

about the aging. It would a big help to casual players if there was an official, detailed, non-confusing explanation -- with examples -- about it included. It seems to be the #1 most-confusing issue about this great game -- look at how many threads get started on it!! Different people on the forum have slightly different opinion about how it works. I think I can speak for a lot of us: Please!
(Plus an explanation of the performance points/rankings changes too.)
