As to the topic at hand, I’m pretty excited for most of the opening slate of releases.
It’s interesting to see them using a similar formula to the 2014 product kick-off, but with a few tweaks.
Dragon adventures: instead of a dragon themed adventure path/campaign it’s a dragon themed adventure anthology.
Forgotten Realms: instead of the Sword Coast guide we’re getting both a players guide and an adventure guide. I’m really interested to see this 2 book approach to settings.
Eberron: whilst not in the 2014 opening slate, it was the first full setting book for 5E, and feels like WotC learnt from that by prioritising it earlier this cycle. I could see a day where Eberron is the default setting for a new edition of DnD.
Starter Set: only differences here are Lost Mines was released before the core rules, other than that, no notes. I’m probably most excited for this, in the hopes that I will get a chance to play it.
