I got the Digital Game Guide as an increase to my pledge in the backer portal, but while my game activation key is available, the guide is not. Is it a digital version of the Prima guide?
I quite like guides when it comes to games with considerable depth and complexity. I remember having my NWN 1&2 manuals printed out on paper for quick reference (spell guides and progression tables, BAB progression, etc). The most useful things to have quick reference to in PoE, I imagine, is talent/ability lists, spell lists and class/spell progression tables. I'm a fan of good Bestiary type in-game resources too, when well implemented. A good bestiary should give at a glance info on strengths/weaknesses in addition to any (optional) blurb.
