One of my favourite things about roleplay is that it doesn't require anything more than a couple of people and an idea. You don't even need the most basic-seeming equipment of pencil, paper and die, really.
There's technological innovations that can help make certain things easier, and there's things that will or might be round the corner that would be cool, but you don't need anything.
1. Whatsapp. I've only recently got the app, when Husbit wanted to make a Deadlands group. It's a really handy way to share ideas between sessions, and also to plan around other commitments.
2. I want one of those 3-d hologram table displays like a lot of sci-fi films have at the moment. Really engaging way of displaying a map.
3. Kettle or percolator. Because coffee. (Or tea when I'm in Wales.)
If you can't get to face to face games, I know there are ways to game online that mimic as best they can the experience of being in the room together, and I think that's a real benefit to technology, but it's not something I've experienced.
