I was looking through the Players Guide a bit, and decided to use a little of the magic as it is set up in the game.  For magic users that use scrolls (and later, books).  Previously, my rule was you need to read it out the first time you use it, take another turn action to secure your scroll, etc.  Since most characters spend part of their morning routine praying for spells, sharpening blades, counting out daggers or checking theives tools, my rules had wizards twiddling their thumbs when they should be the busiest.  So - fix two issues.  Using the PG rules for spell aquisition looks like a nice way to bridge the gap between 'D&D magic' and 'DM James magic'.    During the morning 'drive', so to speak, before y'all break camp to start marching, fighthing, whatever.  Magic users that rely on scrolls can prepare spells per PG rule - 1 per level, plus 1 per Intelligence modifier.  Say your Int modifier is +3.  that is 3+1 so four spells.  If you spend your mornings preparing like the other players and are not interrupted by an encounter (if that happens, everyone will plan according, me included), you can tell me the 4 you have prepared - then, throughout the day, those are ones you can cast without dragging out your scroll - still mind the material, somatic and verbal components.  Should give you a fighting chance at early level, and won't get too wonky until you are so high a level that there might be. umm.  better ways around the issue.  We'll cover this when it's game time, but makes sense that Mages would study particular spells they might find useful.   As always, comments / opinions welcome (and to cut them off, no - I will not honor specific subclasses that say you 'get to prepare x many extra spells' somewhere in some book.  I think this, with the way I run magic, is well benefit enough already).
