There is a lot to read and i have read a lot but not all.
But with everything said about mods. You forgot that, mods that can't be server sided only is a no go.
The book system isn't too bad, how ever, every server run (1-2 month) i have played, i always find a stronger tier weapon that i can make.
Then there is the fact that, the only way you now can level up stuff is to run to book store after book store and mailboxes. It's an endless loop.
At the beginning, it was fun. "OH a book store!" Now its "oh i must take this quest as its a book store poi or a poi with good amount of books" or "i most go in here"
It just get boring fast.
As a person who likes to mine, getting better leveling by using would make the game more, fun.
Same with person who likes to build more than scavenge.
You could make role playing more possible and fun.
If Fun pimps have decided never to go back, then so be it. I just believe, a system of mixed of both books and leveling by doing, could make this game both more fun and interesting.
Please, be nice to each other and always, stay away from the cops, they will not help you! (in the game)
