This evening, before my son went to bed, but after he, my wife and I played 2 games of Settlers of Catan on our Kickstarter produced wooden board, we got around to discussing this upcoming three-day weekend. The current plan is that I'll run another session of Exploring the Outside Inn on Friday night from 1800 to 2200.
On Sunday afternoon, starting at 1400, he'll spend about an hour "converting" the player characters from The Heroes' Gauntlet from DnD 4e back to AD&D 2nd edition. After I started running the Outside Inn campaign, I think he realized his difficulties with his 4e campaign were NOT creativity problems on his part, but simply annoyance at the ruleset itself, which is far too ridiculous to be used as anything more than a source of ideas. But I digress. From about 1500 to 1900 we'll play in the revised version of his world with our revised characters. I recreated Corrin Aledrinker in 2nd edition, keeping as close to the 4e version of him as I could, and dropped from 5 sheets of paper to 1 for a character sheet. I showed my son and his friends, and even those who weren't sure they wanted to switch their characters immediately changed their minds.
Finally, from 1900 to 2300, we'll play in my Star Clans Traveller campaign. My evenings will be spent prepping for Star Clans, with just a few hours devoted to Outside Inn, since I've got enough material for it to keep them busy for weeks. I'll also spend some time going over the rules of AD&D 2nd edition with my son, after his homework is done each night, to help ensure he's ready as well.
Gonna be busy... having fun!
