I'll be playing in a new campaign starting this coming Saturday. We'll be using Google+ Hangout.
Our GM has given us a quick overview of the starting area, and we even get to chose our starting location out of a handful that are detailed. Which means we are in a sandbox right from the start. Should be fun and an Old School feel.
Of course, the actual rules system has yet to be nailed down. As long as it includes dice rolls, some numerical stats and a spell list, I should be able to adapt ;)
Eh, who am I kidding. It's going to be a D&D game, we just need the DM to nail down the system. I'd vote for Crypts & Things, but I think the setting is more standard fantasy, so it probably wouldn't be a good fit.
