My brother and I have dabbled in D&D when we were younger. Also, at the last place where I worked, we had a weekly Pathfinder game session, which was fun.
Usually at our family get-togethers my brother brings a ton of board games to play, like Carcassone, Puerto Rico, etc. We'll be meeting for Thanksgiving and I asked my brother if he thinks we'll be able to get everyone to play some D&D, or some other, easier pen-and-paper RPG. He thinks it will be overly complicated and people will not enjoy it. He mentioned there is a D&D board game which could be a nice introduction.
Is an RPG board game a viable option? Is it / can it be as immersive as pen-and-paper? If we try the pen-and-paper version, is there a particular campaign we should try? We both have no major GM experience, so should we stick to the board game to retain the fun factor?
