I got my hard cover dead-wood versions of HARP SF and Xtreme today. Niceness!
Only one thing, I wish there was a premium heavy weight version of the core rule book too, not just Xtreme. The premium heavy weight is, at a first glance, really nice to flip through, the pages feel durable and all in all the thing is just beautiful.
I get that it may be too much for some to get a b&w heavy weight premium print, but honestly, I'd love one. Less chance of ripping pages and paper, and perhaps even a long life all together.
Not that I'm at all disappointed by the standard hard cover rule book, it just feels a bit ... cheaper than the nice Xtreme heavy weight hard cover.
Idea: You should design a limited edition cover, that is of some colour with a Tintamar logo stamped on top. I'd buy that.
