I've told my D&D club that I'll DM a 4E game on 7th June, the day after its release. Because I'll be busy during the day on 6th June, I'll have less than 24 hours to digest the new rules. Can it be done successfully? Any suggestions on how best to handle this?
I wasn't a playtester so I don't have any advanced knowledge of the new ed. Also, I've avoided looking too closely at the 4E Lite because I don't want to learn anything that turns out to be wrong. I have been looking at official WotC info though.
