I'm back on this. I've been reading through the Technology Guide and I like it for what I need. I'm going to start an in person game in a few weeks, but everyone will start out with a non-spellcasting class. They will also be geographically where we live now in Wisconsin, so it will have a bit of familiarity to it. They won't really know how much the world has changed outside of their little community.
I was thinking about props for the game though. I ran something like this before using the d20 Modern rules and I took a US atlas and scribbled, stained and tore some pages out of it. I also filled it with random phrases from music and religious texts, though the players thought it meant more than it did.
This time though, I'm thinking bigger. I had the idea of buying a cheap small Android tablet that they find in game and give one to them in real life. I can limit it so they only have access to apps I put on it, but it would still have internet connection so they could use wikipedia or Google Maps. Just because they find something in it though, doesn't mean its still there. If they say they are going to charge it, I'll give them a solar panel in game and plug it in out of game. If it runs out of power, they can't use it.
I was looking at tablets though and I'm not sure which one to go for. I was thinking either a cheap Android or the new Fire, since I can get either of those for about $50. That way I don't feel bad if it breaks, or if something happens in game, I can hit it with a hammer or something to show the damage. It might still work, but they will learn to protect it. But if its cheap enough, I won't feel bad.
