Over the past few weeks almost every DnD related blog has some sort of opinion on the DnDNext playtest package and/or some amount of feedback based on their play results. There are always naysayers of course, but the opinions do seem to be generally positive. The thing to remember is that this is a very early version of the game with a lot more yet to come, so chances are that the one thing you would like to see is probably still forthcoming. I don't like having character sheets without the spells detailed on them ... I get it ... it's not really a playtest issue. Patience - all you can really do is to playtest what you've got and provide feedback on that.
Our Sunday night group is going to take advantage of a scheduling opportunity to slip in a week of playtesting on June 17. This coming Sunday we will finish our current adventure arc and will spend a few minutes to discuss who wants to play what character and basically just make sure we are all on the same page. We'll make sure everybody has a copy of the playtest "Players Handbook" to review ahead of time as well. I went ahead and grabbed an enhanced version of the Caves of Chaos map from theweem.com (here) and have started reviewing the adventure in anticipating of leading our brave heroes on the road to glory and gold.
I'm looking forward to it. It's one thing to simply read through the material, but it's something else to actually see it put into action. Mix in an experienced group of players with their own eyes and thoughts and this should be fun.
