geoffwnz: Part of the D&D 50th anniversary celebrations, a Lego Ideas submission got put into production.
Resulted in a 3754 piece kit that has a downloadable one shot adventure that goes with it. There was a live play one shot run when they released the kit. Should be still available on YouTube. It's a pretty good watch if you like that sort of thing. Had Anjali Bhimani as GM with Ginny Di and Luis Carazo as professional players along with the Lego Design Manager and the Lego Ideas creator/submitter as the other two players.
Well, if it was Rolemaster I'd watch it, but D&D? Sheesh, have you looked at their combat rules? And spellcasting?
Runequest would work too.
