How practical are these big books during play at the game table? Do they stay open? Are they bound well for the rigors of play?
I have the suspicion that the binding will start going a bit if you leave it open flat to pages all the time. Mine is still ok, but I can definitely auto-flip to a couple of the pages now in the Borderlands one.
It has one ribbon to mark pages and I use paper for the other ones I want, so it hasn't been too bad for me to use. (No worse than the MM or whatnot).
