GOOGLE DOCS, GOOGLE DOCS, GOOGLE DOCS.
Seriously, Google Documents is amazing. It has been a godsend for my online campaign. Any of my players can open and edit their Campaign Google Doc, and they've used it for session summaries, listing their inventories, quests, rumors (which I actually post to twitter for them to find), and so on. I even have a few documents that only a few players can see so I can dynamically introduce them new information as the campaign progresses.
I feel there should be a spell to instantly create a map, based on what the caster sees. Then, using this map which only applies for a short time (up to two hours, perhaps), the caster can then cast using the map. In this way, cartomancers aren't entirely left behind in combat.
I can picture a cartomancer drawing their own battlemap in the midst of a battle and using that to direct their magic :)
You know, I have more to say.
I miss reading pulpy fiction. For years, me and this old beaten crew of teens wrote absolutely terrible pulp- but I miss the style and the raw, visceral aspects of it. This really brought me back to aliens getting blown apart, undead scrambling around, and my own writing antics.
Tarrentino- this reminds me of some of his work. Perhaps not his dialogue shenanigans, but perhaps a bit of that substance that makes pulp so great.
